“…They are evaluated for frequencies bdow the plasma frequency. The latter two (Hodara and Cohn [4] and Hodara [SI) consider radiation from slab covered planar apertures but do not consider the input admittance problem. Their approach is to assume an aperture distribution of reasonable form and, from the aperture distribution, to determine the resulting radiation intensity in the far field.…”

“…It should be noted that configurations involving anisotropic plasma layers such as considered by Wait [1961], Hodara and Cohn [1962], and others cannot be simulated by the present technique.…”

“…The study of plasma-covered antennas has received a great deal of attention in the last decade [1]- [4]. This attention is, for the most part, due to the obvious application to the re-entry problem.…”
