The problem considered is that of a plane electromagnetic wave approaching from an arbitrary direction a perfectly conducting half-plane in an anisotropic plasma, characterized by a permittivity tensor. The system is such that the wave has a single magnetic field component, which is parallel both to the magneto-static field and the diffracting edge. The work is a simplification of previous work by Jull, involving the use of methods previously developed by the author.
The article proposes an improved mathematical apparatus for studying the amplitudes of the electromagnetic field scattered by an antenna system with a horn feed of pyramidal shape, which is located at the focus of the paraboloid of rotation using the Credo-type ground-based intelligence stations (1RL133). Improvement of the apparatus consists in applying a new method for determining the scattered electromagnetic field reemitted by the irradiator located at the focus of the paraboloid of rotation of the antenna system during normal polarization of the incident plane wave in its plane of incidence, as well as coincidence of the wave and its plane of incidence as a superposition of an arbitrary incidence. The task includes two components: determination of the electromagnetic field in the plane of the focus of the paraboloid of rotation with an arbitrary plane electromagnetic wave falling on it and finding the electromagnetic field scattered from the circular polarization horn feed of the polarized paraboloid with an arbitrary plane electromagnetic wave falling on it. The materials presented in the article and previously received by the author combine the case of an arbitrary fall of an electromagnetic wave, which is a superposition of two cases: the wave is polarized normally to the plane of incidence; coincidence of the polarization of the wave and the plane of its fall. Calculations using the new method will allow evaluating the effect of various elements placed in the plane of focus on the scattering of antenna systems as a whole in any case of a wave falling on a mirror. The construction of radar stations based on a parabolic antenna calculated using a new method will allow one to gain significant advantages over traditional single-polarization radar stations when detecting objects with a small effective dispersion surface and to highlight their information signs.
The problem of the diffraction of a plane electromagnetic wave by a unidirectionally conducting half-plane is solved by transform techniques. A comparison is made with the results previously obtained by Karp.
