Singular integral equations as method of physical regularization

An analysis of ill-posed electrodynamic problems formulated in the form of the 1-st kind Fredholm integral equations (IE) is carried out. It is shown that the Tykhonoff regularization of ill-posed problems ensures stable solutions for electromagnetic field only on the surface, where the 1-st kind Fredholm IE is posed. A well-posed method of physical ...

Applying integral equations for polarization currents to the analysis of waveguide array with projected dielectric elements

The infinite array of stepped plane-parallel waveguides with dielectric inserts and projected dielectric elements, excited by TEM-waves is analyzed in this article using the integral equation for electric field (polarization current) in the projected element and field linking method in the horn; the differential equation is solved using the Galerkin method using vector waves of the corresponding resonator as basis and weight ...
