Excitation of gyrotropic plasma cylinder by a split antenna

Analytical theory of spectrum of H-type, natural oscillations of open cylindric resonator filled with gyrotropic plasma with conducting shell and longitudinal slit of finite width is developed. In the general case of arbitrary parameters of the slit and plasma the task of spectrum and resonator field picture determination is reduced to the system solution on the basis of finite number of homogeneous algebraic equations for Fourier amplitudes of the field azimuthal harmonics
