Radiation from a magnetic line source in a ground plane covered by an anisotropic lossy plasma layer is considered. A magnetostatic field is impressed parallel to the slab and normal to the source. Expressions are obtained by Fourier analysis and the stationary phase procedure for the far-field components of both radiating modes. Numerical results are given for the uniaxial plasma without losses. It is shown that in this case pattern maxima and minima are directly related to ordinary transmission-line reflection conditions expressed in terms of a "transverse-wavelength."
