Abstract
This paper presents the electric shielding effectiveness (SE) of a dual metallic wall with narrow slots when the plane wave is incident. In the analysis, integral equations for aperture electric fields on slots are derived and solved by applying Galerkin's method of moments (MoM). The numerical results show that plane-wave SE depends on both slot lengths and plate spacing for a given frequency. Plane wave SE fluctuates with the spacing of the plate, and the fluctuation period is about 0.5 lambda. A high level of electric SE can be obtained for small slots and low frequencies. Also obtained is the electric SE below 0 dB when the plate spacings are smaller than 0.1 lambda. Experimental measurements are also presented to validate the theory.
