Coupling of surface and volume waves on nonperiodically inhomogeneous impedance rod

In this paper physical efforts of the coupling of longitudinally paraxial wave electromagnetic TM and TE beams falling on image impedance rod with spatially oscillating surface anisotrophic impedance and a surface wave propagating along this rod are theoretically considered. In the present paper we theoretically consider wave coupling in open waveguide formed by plane /spl phi/ =0,/spl pi/,/spl rho//spl ges/R and semicylindrical surface /spl rho/= R, 0
