Abstract The paper presents a numerical simulation of the propagation characteristics of symmetric E-type and H-type waves in microwave circular shielded waveguide with radially inhomogeneous dielectric filling. Using the modified Galerkin method, the calculation of a circular two-layer shielded waveguide was carried out, as a result of which the distribution of the electromagnetic field of the waveguide with linear and parabolic distribution of permeability was determined. The results obtained using the modified Galerkin method were compared with the results obtained using the classical partial domain method, which agree well enough.

Quasi-analytical expression for calculation of breakdown power transmitted by the dominant mode of coaxial-sector waveguide with homogeneous dielectric filling is obtained. Results of quasi-analytical calculation of normalized breakdown power, transmitted by hollow coaxial-sector waveguide for different values of its geometrical sizes and operating wavelength, which can be used in building microwave devices of different application performed on the basis of considered transmission system are represented.
