Session 1: Military equipment EMC testing and infrastructure protection methods
Session chair |
Gavin BarberQinetiQ Ltd |
Biography |
Gavin is the Team Leader for the E3 Test and Evaluation and EM Security team based at QinetiQ Ltd, Farnborough. Gavin heads up a team of engineers developing test methods, providing consultancy for internal and external customers and a test team providing both equipment level EMC testing and mobile HIRF testing both in the UK and Overseas. His specific areas of interest include, research and development of equipment level and whole platform EM test techniques, High Intensity Radiated Field (HIRF) and Product/Equipment EMC design techniques and qualification. Gavin was instrumental in the development of whole aircraft Direct Current Injection (DCI) techniques and worked on reverberation chamber methods in conjunction with the Naval Surface Warfare Center (NSWC). Gavin spent four years within a commercial IT company gaining valuable experience in the areas of EMC design from board to chassis level and in the routes to worldwide commercial product compliance. Gavin has experience of design and verification techniques across a broad spectrum of EM disciplines and has been an active participant in many Military and Commercial aircraft HIRF measurement programmes. Gavin is a member of the Institution of Engineering and Technology (IET). Gavin has presented many technical papers at EMC seminars and conferences both in the UK and oversees, including IEEE and IET sponsored events. |

Session 2
Session Description: EMC Design for the Power & Electronics Applications
Chair: Dr Min Zhang – EMC consultant, Mach One Design ltd, an association of Cherry Clough Consultants
This session covered the design aspect of EMC engineering. Proper design of a product can make the difference between a product passing the EMC tests during the first cycle or not. Traditional EMC design practices have been simply rule-based, but the rules are difficult to implement for various reasons. Three speakers from three industries talked about the EMC design challenges and considerations in this session.
Session 3
Session 3: EMC Simulations
Chair: Tamara Monti, SIMULIA Solution Consultant, 3DS.COM/SIMULIA (Dassault Systemes UK Ltd)
The modelling of electromagnetic systems has become both feasible and affordable in the last twenty years.
This has been enabled by the increasing availability of powerful computing in addition to a number of software systems which enable, not only the solution of the physics of the interaction of electromagnetic fields with the geometry of concern, but also the modelling of that geometry.
There are still a number of challenges in the use and acceptance of the modelling of electromagnetic interactions, including validation, visualisation and assimilation of results and the modelling of diffusive materials and non-linearities.
Session 4
Session Description: Prime Contractor? Don’t leave EMC to the End!
Chair: Professor Ian MacDiarmid – Consultant in Applied Electromagnetics
The session was less about the equipment design and more about the systems design, development and qualification from the prime contractor’s point of view.
Many prime contractors or designers and developers of complex systems do not design and develop the equipment which they integrate into the final system. As such they have to develop specifications which control all the electromagnetic effects with which the equipment has to cope. These include the traditional EMC susceptibility and emission requirements.
In addition, there are a growing number of other electromagnetic effects, including electrostatic charging, induced effects of Lightning, intentional electromagnetic interference etc. Prime contractor organisations also have a responsibility to ensure that systems architecture and installation is designed to ensure that equipment qualification limits are not exceeded.
This session provided an opportunity for speakers to present their approaches to the development of such specifications and systems design, including the responsibility of the prime contractor or integrator to demonstrate the complete system operates safely without electromagnetic incompatibility and without significant disturbance in the presence of an external electromagnetic environment (e.g. High powered radio or radar transmitters or Lightning).

Session 5
Session 5: Practical compliance for manufacturers
Chair: Paul Duxbury
This session discussed practical compliance for manufacturers, and covered all compliance issues, more than just EMC / RED, and of course can cover more than just UK / Euro issues. It was seen more as giving guidance to maybe less experienced companies, pitfalls to look out for, lessons learned, in-house vs external testing, etc.
Session 6
Session 6: EMC Risk Management
Chair: Oskari Leppäaho
EMC risk management can mean different things for a variety of EMC engineers. For some, it means reducing design risks for standard compliance, and for others, it means a risk-based approach to ensure EMC. In its extreme end, the risk-based approach can be used to ensure dependability of electric and electronic systems under electromagnetic disturbances (EMD). This is called EM resilience. In this session, different aspects and advances in EMC risk management are discussed.
In this year’s revision, Mr. Tishehzan discussed a topic on argumenting EM resilience of a system. Then, Dr. Gavrilakis discussed a practical implementation of a risk-based EMC approach in railway systems, and finally Mr. Leppäaho talked about the EMC problematic of large high power drive systems and how to apply risk-based approach there.
