Abstract

We apply multiple scattering equations to study the scattering of electromagnetic waves on a perfectly conducting plane surface with a random dense distribution of hemispherical bosses. We derive a multipole solution up to third order to analyze close range interactions between nearby bosses. Results show significant improvement of accuracy compared with the traditional dipole approximation solution. Absorption on a lossy embossed surface is obtained from the field solution for the perfectly conducting surface. The surface current and absorption enhancement factor are further computed numerically. © 2007 Wiley Periodicals, Inc.

## Abstract A full‐wave analysis is presented for the scattering problem from a frequency‐selective surface (FSS) comprised of a periodic array of conducting patch elements on two dielectric layers. The formulation is carried out in the spectral domain, where the convolution form of the integral eq

## Communicated by W. Sprößig The diffraction of acoustic waves by an infinitely long annular duct having a finite gap on the inner wall is investigated rigorously. The related boundary-value problem is formulated into a modified Wiener-Hopf equation, which is then reduced to a pair of simultaneou
