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

Abstract: 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, and scattering by a filled, overfilled, or void dielectric cavity on a perfectly conducting or a dielectric half-plane… Show more

“…The ohmic absorption by the bump and trench is calculated, and compared with the intrinsic ohmic absorption of an otherwise flat surface. The HIEM code 32 was validated against analytic theory, and it was then applied to cases which defy analytic treatment. The complicated field patterns displayed in Figs.…”

“…The problems of scattering thereby formulated can be solved numerically by utilizing the HIEM introduced in Ref. 32. The HIEM is based on single-layer-potential field representations, efficient evaluation of Sommerfeld integrals, and quadrature rules which produce the single-layer potential with high-order accuracy in spite of Green-function and geometric singularities.…”
