Simulating Electromagnetic Shielding in Electronics and Transportation Applications

Recording date: December 1, 2016

60 min.



Shielding is one of the important design strategies that engineers can use to achieve EMC compliance and protection against Electromagnetic Environmental Effects (E3). Any practical shield used in electronics systems will contain apertures; ventilation holes for thermal cooling, joints in enclosure panels, seams around connectors and other plug-in components. The body of a car or airframe of an aircraft can provide some measure of shielding, but this is compromised by doors, windows, access panels and components interfaced to the airframe such as antennas used for communication and navigation. Composite materials are increasingly used in vehicular applications due to their relatively light weight, but this creates additional challenges for maintaining shielding integrity, such as the direct diffusion of currents through the material in situations such as a lightning strike.

This webinar will explore the electromagnetic simulation of shields at both the electronics and vehicular level, while demonstrating how special modeling techniques applied in the 3D TLM method can be used to improve the efficiency of capturing the important coupling mechanisms.

Dr. David Johns is VP of CST of America. He received his PhD from Nottingham University UK in 1996 for developing a new 3D frequency-domain Transmission-Line Matrix (TLM) method. He has worked on efficient algorithms for simulating thin panel diffusion, field-wire interactions and coupling through apertures. Dr. Johns has over 25 years of experience in developing and applying electromagnetic field simulation. He specializes in EMC, EMI and electromagnetic environmental effects (E3) applications.
