Characterization of flat shielding models
Electronics shields

This chapter  2 , deals with infinites flat shielding models, with high electrical conductivity and finite thickness, submitted to a sine EM plane wave, falling under normal incidence and covering a wide frequency range.

Next sections will be devoted to compute the wave attenuations through a homogeneous, high conductive material, like a copper sheet. Attenuations will be expressed in terms of ratio between electric field (or magnetic field) at screen shadow, over the amplitude of incident field component. Then, this work will be extended to a conductive plane with a circular aperture...
