IET Microwaves, Antennas &Propagation, Volume 15, Issue 10, Page 1159-1170, 12 August 2021., 2021 Abstract Considered is the plane‐wave scattering from and absorption by a thin circular dielectric disk. The analysis uses a set of the singular integral equations for the effective electric and magnetic currents, derived using the generalized boundary conditions on the disk median section.

A numerical solution for the equation of the lifting surface in subsonic flow including tunnel effects [PDF]
INCAS Bulletin, 2011 We employ the images method to establish the lifting surface equation including tunnel effects. We obtain a 2d hypersingular integral and we utilize Gauss-type quadrature formulas to discretize it.

OPERATOR METHOD IN THE PROBLEM OF THE H-POLARIZED WAVE DIFFRACTION BY TWO SEMI-INFINITE GRATINGS PLACED IN THE SAME PLANE [PDF]
Radio Physics and Radio Astronomy, 2021 Purpose: Problem of the H-polarized plane wave diffraction by the structure, which consists of two semi-infinite strip gratings, is considered. The gratings are placed in the same plane. The gap between the gratings is arbitrary. The purpose of the paper

A generalized method for scattering from wide cavities with specified wave functions
IET Microwaves, Antennas &Propagation, Volume 15, Issue 1, Page 69-79, 8 January 2021., 2021 Abstract This study developed a generalized solution based on modal expansion for scattering by large cavities with known wave functions placed in an infinite perfect electric plane. Under the assumption of a large cavity, to reduce simulation time and simplify expressions, the half‐space above cavity with a strong singular Green's function is ...

Extrapolations for hypersingular integrals [PDF]
SCIENTIA SINICA Mathematica, 2015 By using the mildpoint trapezoidal rule a generalized Euler-Maclaurin expansion for computing Hadamard finite part values of the hypersingular integrals with a singular point on the inteval interior is shown, where there are some negative exponential terms of the step size in the expansion. It means that the rule is divergent.
