The scattering of a plane acoustic wave from an impenetrable, soft or hard, prolate or oblate
spheroid is considered. Two different methods are used for the evaluation. In the first, the …

The oblique electromagnetic scattering by a dielectric elliptical cylinder which is coated
eccentrically by a nonconfocal dielectric elliptical cylinder is examined in this work. The …

We consider the problem of counting the number of answers to a first-order formula on a
finite structure. We present and study an extension of first-order logic in which algorithms for …

интегрального уравнения, возникающего в краевой задаче Неймана для уравнения …

In this paper, the finite-element method (FEM) is applied for an exact solution of the
dispersion of hybrid electromagnetic waves excited in a novel combined elliptical …

A numerical method for solving a boundary hypersingular integral equation arising from the
Neumann boundary value problem for the Helmholtz equation is proposed. The proposed …

In this paper, a combinatorial elliptic-circular waveguide is introduced to amplify
electromagnetic waves. The cross-section of this waveguide is elliptic and filled by a …

In this research, the excitation of hybrid electromagnetic waves in a complex dielectric-
plasma waveguide is investigated semianalytically using the perturbation method and …

A closed-form solution to the scattering by an infinite lossless or lossy elliptical cylinder
coating a circular metal core is studied in this work. The obtained solution, free of Mathieu …

An analytical, closed-form solution to the scattering problem from an infinite lossless or lossy
elliptical cylinder coating a circular metal core is treated in this work. The problem is solved …
