This paper investigates the fluctuation spectrum of the surface waves in a semi-infinite plasma, and in a plasma cylinder, with an inhomogeneous boundary layer. It is shown that the correlations of the surface waves are dependent on temperature and density distributions in the boundary layer. The correlation function is determined by temperature values in the points of transition layer, where the longitudinal dielectric permeability becomes equal to zero. Dependence of the obtained correlation function on co-ordinates, in the electrostatic limit, is characterized by the complex correlation length, which is fully determined by the inhomogenity of the plasma density near the boundary.

Propagation of coupled electromagnetic and plasma waves (acoustical) excited by a magnetic ring current in an infinitely long compressible plasma cylinder surrounded by vacuum is studied. It is known that in an incompressible plasma a slow surface wave can propagate only when the electron–plasma frequency, ωP, is higher than the frequency, ω, of the source. However, in the present problem it is shown that under suitable conditions slow surface waves can propagate along the interface of the compressible plasma column and vacuum for values in the range either ωP > ω or ωP < ω. The surface waves for which ωp < ω are supposed to be a new phenomenon. Numerical results for these surface waves have been presented. In addition, an expression for a radiated field is obtained by the usual saddle-point method of integration. The possibility of the existence of leaky waves is also discussed for a special case.

The interaction between incident transverse magnetic (TM) waves and nonuniform plasma cylinder is investigated. The forward and backscattering fields of incident TM microwave are calculated and analyzed by using the scattering matrix model. The dependences of the scattering field on plasma electron density, collision frequency, and incident frequency are analyzed, respectively. The electric field distribution across the section of the plasma cylinder is deduced, visually shown, and discussed.
