Abstract
The ray-tracing technique, in combination with analytical formulations, has been applied to predict the Shielding Effectiveness (SE) of electromagnetic shielded rooms with apertures. This method provides a flexible and efficient way to analyze shielded rooms, especially with electrical large sizes and arbitrary shapes. In this paper, the key factors that affect the performance of a shielded room have been investigated. The simulation results for a typical shielded room, which are in good accordance with experimental results, are presented. The discussions provide a guideline for engineers to optimize the design of shielded rooms for information security.
