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

In this paper, the boundary conditions given by CitationWeinstein (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.
