Abstract

In this study, radiated immunity and emission of a metallic box with apertures have been evaluated through a fast approach. The influence of printed circuit boards inside the enclosure has been studied and also the effect of placing conductive polymer sheets in the housing to characterize the behavior of these materials used nowadays for shielding cabinets. Measurements have been carried out in anechoic chamber to evaluate the approximated technique showing its limitations and advantages. As good agreement has been found between simulations and measurements, this approach can be used for design or optimization purposes with the main advantage of reduced time calculations. © 2009 Wiley Periodicals, Inc.
