ABSTRAKT

An effect of azimuthal dielectric inhomogeneity upon the launched mode attenuation of the hollow dielectric waveguide has been studied using the perturbation method. Estimation of the effect produced by such an inhomogeneity upon the mode attenuation in the hollow dielectric and dielectric-lined waveguides in the case of slow attenuation of a operating HE11 mode has been performed. It is shown that the mode attenuation in both waveguides is not critical to the insignificant inhomogeneities. The linearly polarized HE11 mode in both waveguides is more sensitive to the variation of the dielectric permittivity in the plane of vector E polarization.
