| Abstract: | Conclusions In this paper we have studied the dispersion characteristics of nonpotential surface waves in two- and three-layered magnetized wave-bearing structures. For the case of a vacuum cavity in an infinite plasma, we have obtained an analytic solution for the SW frequency in a regime which is highly nonpotential. We have shown that when the thickness of the plasma layer in a vacuum-plsma-vacuum waveguide is reduced, the dispersion changes its character.We have investigated numerically how magnetic fields, the radii of the cylinders, and the azimuthal wave number affect the LF and HF branches of the spectrum of surface waves.Khar'kov State University.
