Homogenization of corrugated interfaces in electromagnetics
(2005) In Progress in Electromagnetics Research-Pier PIER 55. p.1-31- Abstract
- A surface with periodic corrugations of sufficiently 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.
