Whistler wave propagation in plasma ducts


  • V. I. Karpman,

  • R. N. Kaufman


Analytical theory of whistler wave propagation in axially symmetric ducts with plasma enhancements as well as rarefactions, directed along the constant external magnetic field B, is given. The consideration is based on Maxwell equations in WKB-approximation with the account of the leakage caused by the tunnel transformation of one branch of the perpendicular wave number into another. The conditions of waveguide propagation and the equations for eigenmodes are given. The equations for maximum number of trapped modes are obtained.
