Abstract

This paper addresses shielding effectiveness of multilayer planar shields against oblique incident plane waves in arbitrary polarized and incident direction using transmission line (TL) modelling. New results are presented to confirm the degeneration of the shielding effectiveness due to an oblique incident plane wave. It is also shown that the direction of polarization would be changed when the plane wave penetrates the shield. Previous conclusions for normal incidence can be verified by inserting the normal incidence condition into the new results for oblique incidence
