Oblique Scattering by a Pair of Conducting Half Planes: TM Case

Multipole Expansion of Electromagnetic Scattering Wave by a Small Cylindrical Pore on a Perfect Conducting Semi-infinite Half Space

The scattering of an oblique electromagnetic wave incident on a sub-wavelength circular pore with a finite depth on the surface of a semi-infinite perfect conductor is investigated analytically. We use the method of matched asymptotic expansion to find the multipole structure. The expansion is based on the duality property of the source-free Maxwell equations, and the resultant scattering field...

High-order integral equation methods for problems of scattering by bumps and cavities on half-planes.

This paper presents high-order integral equation methods for the evaluation of electromagnetic wave scattering by dielectric bumps and dielectric cavities on perfectly conducting or dielectric half-planes. In detail, the algorithms introduced in this paper apply to eight classical scattering problems, namely, scattering by a dielectric bump on a perfectly conducting or a dielectric half-plane, ...

Scattering by a Tilted Strip Buried in a Lossy Half-Space at Oblique Incidence

The analysis of the scattering by a tilted perfectly conducting strip buried in a lossy halfspace at oblique incidence is formulated as an electric field integral equation (EFIE) in the spectral domain and discretized by means of Galerkin’s method with Chebyshev polynomials basis functions weighted with the edge behaviour of the surface current density on the strip. In this way, a convergence o...

Oblique Rayleigh wave scattering by a cylindrical cavity

The problem of oblique wave scattering of a Rayleigh wave by a cylindrical cavity in an elastic half-space is solved using the multipole expansion method. Whereas in the analogous water-wave problem a single scalar field is expressed as an infinite multipole expansion, and in the Rayleigh wave case with normal incidence two scalar fields suffice, here we require three coupled scalar multipole e...
