Mathematical simulation of semitransparent layered thin-walled waveguides with the use of averaged two-sided 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.

Shielding of a magnetic pulse by the multilayer film shield with alternating magnetic and nonmagnetic layers

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.
