Abstract :
This paper describes a technique whereby feed equivalent surface currents generated in the ESL BOR (Body of Revolution) code are linked to the NEC-REF code to generate reflector surface currents, and then both sets of surface currents are linked to the NEC-BSC code to analyze a scattering problem.
