Abstract

Abstract

Transmission line method is extended to include multi-mode transverse electric cavity modes which are introduced by aperture coupling and it is used to analyze the coupling effectiveness of double layer rectangular enclosure with aperture to the wide band high power microwave electromagnetic pulse. The electric shielding effectiveness of single layer enclosure with aperture is compared with that of double layer enclosure with apertures. The simulation results show that: shielding effectiveness can be improved greatly with double layer shielding and it is worse on the resonance frequency of cavity modes. On the condition of aperture-cavity resonance, shielding effectiveness drops significantly in the center of inner cavity. FDTD result is compare to the results of transmission line model. F
