The following paper is about the determination of the transfer impedance measured in the 1 GHz triaxial cell with two different configurations for different types of sleeves. Indeed, being a very important subject, the design of a sleeve allows us to ensure better shielding efficiency against electromagnetic disturbances. The transmission parameters (S21) will be transformed into transfer impedance by using the passage formula and adapted to the structure of the triaxial 1 GHz cell. The comparison of the transfer impedance for both configurations was studied. The first configuration includes the 1 GHz triaxial cell with two matching systems (internal and external), whereas the second configuration includes an internal matching system with an external short-circuit.
10 : 00 - 10 : 30 Lightweight Convolutional Neural Network for DC Series Arc Detection in Rail Applications
Jack Larkin, Danny Seeley, Paul Evans, Minglei You, Peter Christopher, Steve Greedy – University of Nottingham, United Kingdom
Managing and responding to DC series arcs is becoming increasingly relevant due to the increased adoption of high-voltage electrified railway networks. In these faults, current flows through the air between conductors as high temperature plasma, posing significant fire hazard and safety risks. In our work we propose a shallow Convolutional Neural Network (CNN) that can differentiate between healthy and arcing current measurements with an F1 score of 0.94. We also measure computational complexity, 211 million Floating Point Operations, to anticipate implementation on single-board computer devices.

11:00 - 11:30 Novel Method for EMC Testing of Large Automotive Subsystems
Mayur Yeola, Abhijit Mulay – Automotive Research Association of India (ARAI), India
The automotive industry is currently experiencing rapid technological advancements, particularly in the realm of electric vehicles (EVs). These vehicles represent intricate and dynamic systems, comprised of various components that interact in complex ways. As the number of EVs on roads continues to rise, manufacturers are compelled to innovate and develop practical features for electric vehicles. In this context, conducting Electromagnetic Compatibility (EMC) testing on all powertrain components under real-world conditions becomes critically important. This paper will propose EMC testing methodologies specifically for large EV subsystems, such as traction batteries, Battery Thermal Management Systems (BTMS), and HVAC systems. Additionally, it will highlight instances where results from real-world scenarios diverge from those obtained in bench-level setups, and will detail the testing methodologies for these large components, ultimately aiming to yield more accurate and applicable results.

09:30 - 10:30 Workshop #1.1
Modeling and Optimization of EMC in Electric Vehicle Power Electronics #1
Dr. Bibhu Prasad Nayak, Dr. Jan Hansen – Graz University of Technology, Austria
With the proliferation of EVs, power electronics plays a key role in the powertrain. Submodules like converters and inverters are an integral part of any electric vehicle design. The functional challenge to achieve higher efficiency and lower losses pushes designs toward faster switching, which brings more electromagnetic (EMC) challenges. Before a vehicle comes to market, it must undergo EMC tests and meet emission and immunity regulations. To meet these standards, either multiple EMC lab iterations are required or EMC simulation must be performed before the prototype is ready, known as EMC frontloading. A key challenge of EMC simulation is accurately modeling the noise source and the noise propagation path. As subsystems consist of multiple PCBs, hundreds of components, metal housings, and test harnesses, the problem becomes very complex and time-consuming. This calls for EM-driven methods that are computationally effective, focusing only on critical coupling and propagation paths. In the first part of this session, we address how to build an EMC simulation setup in a full-wave, circuit-coupled environment. We demonstrate a conducted emission setup for an inverter driving a motor, from component-level modeling to the full system model. The second part focuses on source modeling, which is another critical aspect of EMC simulation. In power-electronics-driven subsystems, MOSFET switching is a key EMC noise source, but manufacturers often do not provide EMC-relevant model parameters. We show which parts of the switch model are important and introduce a circuit-coupled full-wave approach to handle switching behavior. In the third part, we focus on optimization driven by machine learning. Machine-learning-based methods provide an alternative to traditional optimization, enabling faster design space exploration while avoiding repeated complex simulations.
09:30 - 10:00 Component & Source Modeling
This presentation starts with passive component modeling, showing how equivalent network models for capacitors and inductors can be derived from impedance measurements. It then demonstrates EMC-relevant switch modeling, highlighting critical source parameters such as rise/fall time and ringing that dominate conducted and radiated emissions.
10:00 - 10:30 System simulation - circuit
Network-level system simulation is presented as a first step to estimate filter topology, component count, and volume. Below a few MHz, SPICE-level models are shown to be sufficiently accurate for conducted emission prediction, and a complete workflow for conducted emission analysis is demonstrated.

11:00 - 11:30 System simulation - circuit coupled EM
At higher frequencies, PCB layout and interconnect parasitics become critical and can significantly alter the EMC noise source. This presentation demonstrates circuit-coupled full-wave EM simulation as an effective approach to accurately capture parasitics and predict emissions in complex power electronic systems.
11:30 - 12:30 Machine Learning & optimisation
This presentation explores machine-learning-driven optimization techniques for EMC design. By learning from simulation data, these methods enable rapid design space exploration and performance optimization while significantly reducing the need for repeated full-wave simulations.

Mark Emery – HORIBA MIRA, UK
As vehicle technology continues to evolve and corresponding international standards are updated to compensate, so too must the directive that governs safe, compliant design. We explore the background to automotive legislation UNECE Regulation 10, the Type Approval regulatory certification process and the recently released changes within R10.07 along with the forthcoming supplements and future developments planned for R10.08. This presentation outlines what these changes mean for manufacturers, test labs, and type approval authorities.
14:00 - 14:30 The Emergence of Hybrid EMC and Antenna Measurement Chambers in the Automotive Industry
Ben Hodges – ETS-Lindgren, Finland
EMC testing has been a standard part of the certification and homologation process in the automotive industry for several decades, and in that time several standards have been developed to support the conducted and radiated emission and immunity measurement of components and full vehicles across a steadily increasing frequency range. More recently, the introduction of advanced driver assistance and communication systems has prompted the need for antenna pattern and over the air (OTA) communication measurements. In this presentation we will look at a developing trend toward the use of multi-functional facilities and the pros and cons of such an approach.
14:30 - 15:00 Automotive EMC Testing Under Dynamic Driving Conditions
Bennet Boeker – AVL Zöllner GmbH
Electric drive units generate significantly higher and higher frequency electromagnetic interference than combustion engines, with EMC strongly affected by operating conditions such as acceleration and braking. Modern vehicles must also integrate ADAS technologies that rely on sensitive RF electronics vulnerable to interference from high power electric components. To ensure vehicle safety, the EMC performance of key electric powertrain components must be evaluated in environments that replicate real driving conditions. This presentation reviews the main factors influencing EMC in electric powertrains and explores solutions for creating more realistic and representative test scenarios.

Electromagnetic Shielding - Principles and Reality
Prof. Andy Marvin – University of York, United Kingdom
A brief introduction to the principles of shielding effectiveness followed by a review of some practical issues and results. Finishing with an overview of shielding standards. “What is the Shielding Effectiveness (SE) of this enclosure?” is an easy question, but the answer is somewhat more complicated. In simple terms the SE of an enclosure is the ratio of energy coupled between a source and a victim (receiving antenna) without the enclosure to that with the enclosure present. The aim of this workshop is to help you understand the principles that underlie this complexity without too much mathematics. This is supported with examples of practical measurements that illustrate the effects discussed. Finally we will conclude with an overview of the SE measurement standards currently available and their applications.

The challenges associated with the measurement of radiated fields
from power system substations
Prof. David Thomas – University of Nottingham, United Kingdom
Multi-level converters are being increasingly used in power system substations as part of flexible AC transmission or high voltage DC. There is then a possibility of radiated interference due to the large physical size of high voltage substations. To date there are no standards for assessing substation radiated emissions, but CIGRE technical brochure 391 is generally used as a guide to ensure some sort of electromagnetic compatibility compliance. This workshop will discuss the philosophy behind the approach given in CIGRE technical brochure 391 and the potential challenges associated with completing the radiated electromagnetic emission assessment according to the guide.

This is not rocket science but an easy-to-understand application of PCB geometry.
09:30 - 10:30 Effective PCB Design: Techniques to Improve Performance
As IC geometries continue to shrink and switching speeds increase, designing electromagnetic systems and printed circuit boards to meet the required signal integrity and EMC specifications has become even more challenging. A new design methodology is required. Specifically, the utilization of an electromagnetic physics-based design methodology to control the field energy in your design will be discussed. This training module will review the development process and provide guidelines for building successful, cost-effective printed circuit boards. After introducing EM field behavior, this course will describe several effective methods for designing the spaces used to direct EM fields on a PCB. Simple rules for managing these fields will be described, based on one fundamental behavior. How fast does the switch change states? This defines the requirements for the power distribution and the geometry of the space between the output of the switch and the receiver. Several real-world examples of the use of these principles, both for designing compliant boards and for analyzing EMC failures are presented.

Dan Beeker – System Solution Specialists, USA
13:30 - 15:00 Feeding the Beast: Consumption-based PCB design
This session is a step-by-step guideline for determining the PCB design requirements based on device energy consumption requirements. Wave cycle times and transmission line capacity form the basis of this philosophy. The session will begin with a review of EM field behavior and transmission line design, then outline a process for analyzing the real power delivery challenge posed by a high-performance microprocessor. Starting with the DC current specification, we will use the device package pinout to determine the necessary PCB networks required to support the delivery of power to the device. The course will center on the LS1043 Network processor, with a focus on the core power supply requirements (7 A/uS). The package pinout and clock frequency will be used to determine the real "coulombs per wave cycle" that the PDN must support. This will then be used to design both local storage requirements and connecting structures. A spreadsheet will be presented, which can be used to do a quantitative analysis of the transmission line capability based on the impedance and length, so the number of wave cycles needed to deliver the required charge. This perspective can be used in the initial design phase or to evaluate existing designs. EMC test results from a production design, MPC-LS-VNP-MOD, using this approach, will be presented.

11:00 - 11:30 EMC issues in DC-output power electronics
Arun Khilnani – The University of Nottingham, United Kingdom
Growing renewable energy adoption is increasing reliance on fast-switching DC-output power converters. Integrating these converters with new DC grids within the existing AC infrastructure is introducing more EMI, both among DC converters and across AC–DC interconnections. Maintaining EMC then requires compliant design, filtering, and coordination to maintain power quality and system reliability. Yet, we do not have standards to regulate EMC within DC grids. This presentation look ats the immediate issues we need to research to ensure greater integration of DC converters into the DC grid.
11:30 - 12:00 Tales and trends from the front line of EMC testing: pass rates, observed failures, and root cause analysis from 10 years of commercial laboratory operation
James Pawson – Unit 3 Compliance Ltd, United Kingdom
EMC has a reputation as a difficult discipline and the outcome of testing is often uncertain. Most small and medium companies design equipment with little EMC knowledge and simulation tools are rarely used. EMC test failures are frequent, causes are poorly understood, and mistakes are frequently made or even repeated. Working extensively with such small companies, including EMC analysis and problem solving, has given Unit 3 Compliance a unique insight into the most problematic tests, common failures, and most effective fixes. This talk will give a simple statistical overview of the products we have tested over the last 10 years including category of equipment, failure rates per test, failures per product, root cause analysis of failures, specific examples from some of the work that we have carried out, the impact of simple EMC design reviews on test outcomes. This real world data and analysis would be of value to anyone designing equipment today.

A brief overview of the application of Def Stan 59-411 EMC tests
Chris Nicholas – Threysus, United Kingdom
Rapid advancement of modern electronics and the widespread availability of high-performance consumer technologies have significantly influenced the design and deployment of equipment in military and defence environments. The boundaries between traditional military-grade hardware and commercial electronics have become increasingly blurred. This shift has been driven by the performance, availability, and cost advantages offered by Commercial Off-The-Shelf (COTS) technologies, which are now frequently incorporated into systems that must operate within mission-critical defence platforms. We look at the Mil/Def standards and a risk assessment method for comparison.
15:30 - 16:15 Understanding the need for Def/Mil EMC Tests
Chris Nicholas – Threysus, United Kingdom
Introduction to the Def/Mil EMC tests and why they are different. Military and Defence EMC (Electromagnetic Compatibility) testing is significantly more rigorous than the commercial standards. While commercial rules focus on interference and immunity, Def/Mil standards are designed to ensure equipment survivability in high-threat environments where equipment failure is not just an inconvenience.
16:15 - 17:00 Managing the risks of using COTS equipment
Richard Hardy – TUV SUD, United Kingdom
Boundaries between traditional military electronics and commercial electronics have become increasingly blurred. This is driven by the performance, availability, and cost advantages offered by COTS technologies. These now are incorporated into systems that must operate within mission-critical defence platforms. Integrating COTS into military platforms creates a "compliance gap." While the performance is high, the electromagnetic assurance is low. To manage this without the extreme cost of full military redesign, a Risk Assessment Method is used to determine if the commercial equipment can survive the mission.
