Abstract

In this paper, the transmission line method (TLM) is applied to calculate the shielding effectiveness (SE) of a metallic enclosure with apertures. The cases of high-order modes and 2-layer shield model are considered. The resonant frequency of the enclosure with installation of PCB is predicted by the perturbation method. Conclusions are drawn that the SE can be quickly calculated by the TLM and the SE of aperture array is higher than single one´s. It is also worth noticing that a 2-layer enclosure is capable to improve the SE significantly. Also, Good agreement of the resonant frequency is obtained between simulated result by CST and calculated result by the perturbation method.
