TL;DR: The boundary value problem on the penetration of electromagnetic waves from a thin-walled cylindrical waveguide into the environment was solved with the use of averaged boundary conditions.
Abstract: The boundary-value problem on the penetration of electromagnetic waves from a thin-walled cylindrical waveguide into the environment was solved with the use of averaged boundary conditions. The multilayer wall of the waveguide was considered as an ideally thin cylindrical surface, the complex material structure of which was described with the use of special two-sided boundary conditions. The dispersion equation determining the constants of propagation of partial waves in the waveguide was solved by the method of numerical minimization of the function of two variables. Results of calculation of the attenuation of the electromagnetic field penetrating from the waveguide into the environment as compared to the field of the corresponding mode inside the waveguide are presented.

TL;DR: In this article, a model of the heating of the half-space medium as a result of the electromagnetic-to-thermal and vice versa energy conversion has been considered, and a numerical study of heating depending on the delay time has been made.
Abstract: We have solved the problem on the propagation of a high-frequency electromagnetic field in a half-space filled with a medium with delayed electric and magnetic polarizations and conduction currents under the action on the half-space of an arbitrary combination of plane fields, as well as of surface currents and charges distributed over the half-space surface. A model of the heating of the half-space medium as a result of the electromagnetic-to-thermal and vice versa energy conversion has been considered. A numerical study of the heating depending on the delay time has been made.

Abstract: The edge problem of the penetration of the magnetic field pulse with millisecond and microsecond front duration inside a multilayer circular cylindrical shield has been solved by the analytical methods. The mathematical model of the shielding problem is based on the use of the Laplace equation and nonclassical two-sided boundary conditions that connect magnetic fields on both sides of the thin-wall shield. A structure of the magnetic pulse inside the shield and shielding efficiency has been studied numerically depending on the layering structure of the shield at fixed thickness of the shield.
