Surface Flute Waves Propagating in Non-Isotropic Plasma Filled Waveguides

Abstract

This Chapter is devoted to the theory of surface waves propagating across the axis of symmetry in non-isotropic cylindrical metal waveguides with magneto-active plasma filling. The presented theoretical results illustrate: how can spatial non-uniformity of both the plasma density and the external magnetic field affect the dispersion properties of these waves. These problems have been solved both analytically and numerically. The analytical study of the obtained equations is carried out by the method of successive approximation; adequacy of this approach is proved here as well. Numerical evaluations of the possibilities to experimentally observe the phenomena, which accompany the propagation of these waves in non-uniform plasma filled waveguides, are carried out.
