Calculation of a double reflector Cassegrain antenna by physical optics method with taking into account multiple reflections between the and subreflector was performed. It shown that convergence characteristics (gain, efficiency, side-lobe level) increase accounting is observed. To check same calculated electric field integral equation unknown surface currents on sub-reflector. The comparison s...

This paper1 continues the study of a class of compact convex hypersurfaces in R n+1 , n ≥ 1, which are boundaries of compact convex bodies obtained by taking the intersection of (solid) confocal paraboloids of revolution. Such hypersurfaces are called reflectors. In R3 reflectors arise naturally in geometrical optics and are used in design of light reflectors and reflector antennas. They are al...
