This paper describes the propagation models of the transverse electrical wave and current distribution in the superconductor cylindrical waveguide based on superconductor electromagnetic theory and the Meissner model.

Characteristics of low-frequency modes in a cylindrical waveguide filled with plasma;

By means of fluid model and linear field theory,the dispersion equation of the electromagnetic wave propagation along a cylindrical waveguide filled with an infinitely thin annular plasma.

This paper deals with the problem of truncating the open boundaries of cylindrical waveguides under the rectangular coordinate system, and gives the CPML’s construction parameters.

The electromagnetic fields components of the TE wave mode of a half-round waveguide are obtained theoretically,by using the conclusions of the rectangle and the circular waveguide,the superposition method and the mirror image method etc.

The magnetic field in the intersection area of two parallel long cylindrical conductors with opposed current is discussed, and it is found that the magnetic field in the intersection area is uniform.
