Sammanfattning
A surface with periodic corrugations of suffciently small periodicity is shown
to be electromagnetically equivalent to an inhomogeneous transition region
(slab). Explicit expressions for the inhomogeneous transition region are found
for one-dimensional corrugations and for two-dimensional corrugations a local
elliptic problem has to be solved in order to find the equivalent electromagnetic
properties. The homogenized surface can be characterized by its surface
impedance dyadic or its reflection dyadic. A few numerical examples illustrate
the theory.
