Electromagnetic Shielding: Concepts and Applications

Every electronic equipment use some type of shielding, and from a theoretical point of view, electromagnetic shielding is among the difficult areas of EMC. The presentations is introducing basic shielding concepts, insisting on their practical limitations, and presents the typical engineering problems associated with shielding. Among the aspects discussed are the materials used for shielding, chassis resonances, shielding integrity problems (seams, joints, apertures, perf patterns, etc.), aperture coupling and shield’s grounding.

Speaker(s): Dr. Sergiu Radu of Oracle,
