The scattering problem of transverse electric wave from a dielectric biconvex cylinder buried in a shallow circular trough of a ground plane is investigated and a rigorous series solution is also derived. Based on the region-matching method, the analysed region is decomposed into two subregions by introducing a semi-circular auxiliary boundary. The magnetic field of each subregion is expressed in terms of cylindrical wave functions with unknown expansion coefficients. After imposing the matching conditions and the boundary condition on the trough surface with the aid of Graf's addition theorem, the unknown coefficients are determined. Comparisons with published data for a dielectric circular cylinder case show very good agreement. Visible effects of depth-to-half-width ratios of a dielectric biconvex cylinder on echo width, far-field pattern and near-field distribution are illustrated in graphical form.read more

TL;DR: In this paper, the authors considered the transient, or time-domain, scattering problem of a two-dimensional overfilled cavity embedded in an impedance ground plane and proposed an artificial boundary condition on a semicircle enclosing the cavity, which couples the fields from the infinite exterior domain to those fields inside.
