A quasi-optical approximation for absorbing media having dispersion relations with repeated solutions


  • J. A. Bennett


A quasi-optical approximation is constructed for waves in media for which the dispersion relation has repeated solutions, the order of repetition being constant throughout the medium. By a suitable choice of the basis vectors representing the polarizations corresponding to the repeated solution, the equations for the amplitude may sometimes be uncoupled. An important application is to radio waves in an isotropic absorbing medium.
