Dissipation in Frequency Selective Structures
(2002) In Technical Report LUTEDX/(TEAT-7107)/1-31/(2002)- Abstract
- 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 metallic plate. The dissipation in the dielectric parts
is modelled by the complex permittivity. The dissipation on the metallic
structure arises both on the plane metallic surface and on the metallic walls
of the apertures.

The method used to analyze the FSS is based on the mode matching technique
and the Finite Element Method (FEM). The apertures are treated as
waveguides. The field are expanded in Floquet modes and waveguide modes,
and scattering matrices are derived. The attenuation and the power losses
are calculated for a number of different FSS, and based on these results the
performance of an FSS with losses is discussed. (Less)
