The electromagnetic properties of a model of a re-entry plasma layer are determined using the linearized hydrodynamic equations for a single fluid warm plasma medium. The model consists of a perfectly conducting plane of infinite extent, representing the surface of a space vehicle, covered by a warm plasma layer of uniform density. The total fields excited by a magnetic line source located on the conducting plane are computed by Fourier transform techniques. Expressions are obtained for the energy transported by the radiation field and by the waves guided along the plasma layer. Numerical results are presented showing the dependence of the energy transport on frequency and electron temperature. In addition, the radiation pattern of the far zone field is computed for various values of frequency and electron temperature. Author
