Manipulation of backscattering from a dielectric cylinder of triangular cross-section using the interplay of go-like ray effects and resonances
(Institute of Electrical and Electronics Engineers, 2015)
A triangular dielectric cylinder (dielectric prism) of the size, in cross-section, comparable to or moderately larger than the wavelength is a scatterer, which blends together two different types of electromagnetic behavior: ...
Validation of higher-order approximations and boundary conditions for lossy conducting bodies
(Institute of Electrical and Electronics Engineers, 2014-09)
The problem of high-frequency diffraction by a smooth lossy body with high conductivity is considered. In addition to the geometrical optics approximation, additional asymptotic terms are derived to take into account the ...
Validity and limitations of the median-line integral equation technique in the scattering by material strips of sub-wavellength thickness
(Institute of Electrical and Electronics Engineers, 2014-07)
Considered is the 2-D scattering of a plane wave by a thin flat material strip. The data obtained by using the empirical method of generalized boundary conditions and singular integral equations on the strip median line ...
