Synthesis of Loaded N-Port Scatterers

Abstract

The report gives methods for designing reactively loaded N-port scatterers to have desired scattering pattern characteristics. A method for obtaining a least-squares approximation to a desired magnitude radiation pattern, with the restriction that port currents are real, is developed. A procedure for obtaining maximum gain, with the restriction that the port currents are real, is also described. Conducting bodies can be reactively loaded to make any real port current the dominant port mode of that body. If the body is electrically small or of intermediate size, and if a sufficient number of ports are chosen, then the scattered field pattern is approximately the same as the synthesized pattern. A number of numerical examples are given for a body consisting of a wire triangle with two cross wires, on which four ports are defined. Computer programs with sample input - output data are given for each procedure discussed.
