Dissipation in Frequency Selective Structures
Dissipation in Frequency Selective Structures (FSS) of aperture/slot type is studied. The FSS consists of an arbitrary number of aperture layers and dielectric layers. An aperture layer consists of a conducting plate with a periodic array of apertures, with arbitrary cross-section. The dissipation in an FSS is due to losses in the dielectric material, and losses due to finite conductivity in the me
