Abstract: | The dispersion characteristics and the field structure of axisymmetric modes channeled by a high-density plasma inhomogeneity stretching along the external magnetic field are determined in the whistler range. The feasibility of matching a small antenna to the background plasma by means of plasma inhomogeneity is demonstrated theoretically and experimentally.Nizhni Novgorod State University.
