Calculation of Electromagnetic Field in Near Field Zone of Reflector Antenna With Edge Radar Absorbing Coating

Abstract

In the paper technique of electromagnetic field calculation in near-field zone of parabolic antenna with reflector edges covered by toroidal radar absorbing coating is presented. The calculation technique is based on the applying of the integral representations obtained using Lorentz lemma. For calculation of the reflector edge parts contribution to the total antenna field the solution of model scattering problem for half-plane with radar absorbing cylinder on the edge, sounded by plane electromagnetic wave, is used. Calculation results for different values of radius of radar absorbing coatings are presented.
