Scattering of Plane Waves at the Junction of Two Corrugated Half-Planes

Abstract

In this paper, the boundary conditions given by Weinstein ( 1969) are employed to simulate two corrugated half-planes with the same slot height but different slot width. The scattering mechanism at the junction of these half-planes is investigated via the Fourier transform technique, which leads to two coupled Wiener - Hopf equations. The solution of the Wiener - Hopf system is obtained by the Daniele - Khrapkov method and some numerical results are presented about the analysis of the scattered field.
