26 September 1997 Scattering from planar surfaces with magnetic and thermal fluctuations
Author Affiliations +
The formalism to study the scattering by a planar interface with spatial variations in the refraction index is developed. The results obtained are applied to two cases of theoretical interests, which are not currently implemented with this method: thermal gratings and spatial variations in the magnetic permeability. Surface impedance is plotted as a function of the spatial coordinate and the angular component of incident field. Also, scattered intensity is calculated for each case using a Gaussian beam as incident field.
