Wave spectrum of a conducting cylinder in an isotropic plasma

Resumo

The boundary value problem of the propagation of an electromagnetic field along a cylindrical conductor in an isotropic plasma medium has been solved by the impedance method. The boundedness of the wave spectrum of such a guiding structure has been shown. The spectrum includes fast intrinsic wave E₀₁ and extrinsic hybrid waves HE_nm and EH_nm, both fast and slow ones, their countable set being determined by the azimuthal index.
