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)

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. (Less)
