Scattering from dielectric frequency selective structures
(2001) In Technical Report LUTEDX/(TEAT-7101)/1-23/(2001)- Abstract
- 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... (More) - A plane wave impinges on a laterally double-periodic inhomogeneous lossy

method showing very good agreement. The method is also used on a
pyramidal absorber-like structure. (Less)
