Scattering from dielectric frequency selective structures

Research output: Book/ReportReport


A plane wave impinges on a laterally double-periodic inhomogeneous lossy
dielectric structure. Using a wave splitting approach, and an expansion of the
fields and permittivity in global and local basis functions, respectively, the
scattered fields are determined via a propagator. The formulation is useful
for a permittivity which varies abruptly as well as in a continuous fashion.
A subdomain basis for the constitutive parameter is preferred to an entire
domain basis. Calculated results are compared with experimental data for
a slab with domains of a piecewise homogeneous permittivity. The agreement
is good considering the error sources in the experiment. The results
are in a special case also compared with results obtained by an entirely different
method showing very good agreement. The method is also used on a
pyramidal absorber-like structure.
