Abstract. At present, large antennas of deep space deep space communication with beam-waveguides are being designed and developed in response to the surge of interest in deep space exploration. Electromagnetic analysis of such structures traditionally causes difficulties and requires powerful computers to obtain an accurate solution. The results of vector EM field calculation and efficiency evaluation of electrically large reflector antennas and beam-waveguides (BWG) using the Riemann-Silberstein (RS) vectors are presented in this paper. Electromagnetic field propagation and radiation are analyzed considering distorted mirrors and BWG metal enclosure. This allows to obtain a more accurate solution for such systems and determine requirements for mirrors and enclosures in order to minimize distortions. It is shown that for a system of scattering structures it is enough to take into account only one RS vector to obtain a full field. Theoretical characteristics of the dual-reflector Cassegrain antenna are compared to the simulated and experimental results.

Key words: Antennas, aperture antennas, beam-waveguide, computational electromagnetics, electromagnetic fields, electromagnetic radiation, Riemann-Silberstein vectors, spherical harmonics, spherical wave expansion.
