PROJECT TITLE :
Manipulation of Backscattering From a Dielectric Cylinder of Triangular Cross-Section Using the Interplay of GO-Like Ray Effects and Resonances
A triangular dielectric cylinder (dielectric prism) of the scale, in cross-section, corresponding to or moderately larger than the wavelength is a scatterer, that blends together two totally different types of electromagnetic behavior: geometrical optics (GO) and resonance. As shown during this paper, the primary is accountable, for instance, for enhanced reflection from an isosceles ninety° prism, if illuminated from the bottom. The second is responsible for the peaks in the total scattering and absorption cross-sections (ACSs) at the natural-mode frequencies. The numerical analysis is performed by solving the well-conditioned Muller-type boundary integral equation (IE) discretized using an algorithm with controlled accuracy.
