#### Integral-equation study of ray effects and natural-mode resonances in a 2-D dielectric prism

(IEEE, 2015)

We analyze the interplay of two different types of electromagnetic behavior demonstrated by a 2-D dielectric prism: Geometrical Optics and resonance. As it is shown, the first is responsible, for instance, for enhanced ...

#### Validity of generalized boundary conditions and singular integral equation method in the scattering of light by thin dielectric strips

(IEEE, 2014)

We consider the two-dimensional (2D) scattering of a plane wave of light by a thin flat dielectric nanostrip. Empirical method of generalized boundary conditions and singular integral equations on the strip median line is ...

#### Wave scattering by one and many thin material strips: singular integral equations, Meshless Nystrom discretization, and periodicity caused resonances

(IEEE, 2014)

We consider the medial-line singular-integral equation technique for the analysis of the scattering by multiple thin material strips. Their discretization is performed using the Nystrom-type scheme that guarantees convergence. ...
