This report is devoted to the investigation of dispersion properties and axial field structure of the axial-symmetric high-frequency electromagnetic E -waves that propagate in coaxial magnetized waveguide structure, partially filled with by radially non-uniform plasma. On the axis of the waveguide there is a metal rod of radius R1, through which the direct current flows. This current creates a radially non-uniform azimuth magnetic field. The plasma layer occupies the region R1 < r < R2 . Between plasma and external metal wall of the waveguide (radius R3 ) is vacuum gap. The plasma is considered in a hydrodynamic approach as cold collisionless medium. The influence of the geometric parameters of waveguide structure, plasma non-uniformity, direction and value of the direct current on phase characteristics, axial field structure and wave power flux of axial-symmetric Е-waves is considered.
