About the Project

Electromagnetic shielding is important for all kinds of electronic equipment to prevent interference propagating. Most existing standards measure empty enclosures. We have shown that the shielding in a practical enclosure is dependent on contents [1-3]. The aim of this project would be to develop measurement techniques for resonant and sub-resonant enclosures which allow the overall performance of a practical enclosure to be evaluated in terms of risk of interference. The project would involve measurement, analytical solutions, and computer models of prototype measurement techniques applied to shielded enclosures.
