This report is devoted to the investigation of dispersion properties, attenuation coefficient and radial wave field structure of high-frequency electromagnetic wave that propagates in coaxial magnetized waveguide structure with non-uniform azimuth magnetic field, partially filled by radial non-uniform collisional plasma. The influence of geometric parameters of waveguide structure, plasma non-uniformity, effective collision rate, direction and value of azimuth magnetic field on phase characteristics, attenuation coefficient and radial wave field structure of the considered wave is studied. It was shown that it is possible to control effectively the dispersion properties and spatial attenuation of the considered wave by varying the value and direction of external azimuth magnetic field.
