Homogenization of corrugated interfaces in electromagnetics

Kristensson, Gerhard LU (2004) In Technical Report LUTEDX/(TEAT-7122)/1-29/(2004) TEAT-7122.
Abstract
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.
