Theoretical studies have been made into the relativistic drive bunch generation of a wakefield in a cylindrical waveguide filled with a transversely inhomogeneous plasma. According to the model used, the transversely inhomogeneous plasma is considered as a combination of tubular plasma and the plasma background of different density. Analytical expressions have been derived for the excited radial and axial electric field components, and for the azimuthal magnetic field component. The dispersion of the plasma waveguide under study, as well as the topography of the electromagnetic field components of the TM-eigenwaves, resonant with the bunch, have been investigated. Longitudinal and transverse amplitude distribution structures of the axial and radial wakefields have been determined. Spectrum analysis of the longitudinal and transverse wakefields has been performed with the result that their frequency content has been determined.
