Analysis of radiation from two separate axisymmetric horns using the method of moments

A method of moments (MoM) technique is described for analyzing the radiation from two parallel axisymmetric horns whose apertures are non-coplanar. Using the equivalence principle and appropriate boundary conditions, a set of integral equations is obtained with currents on the horn surfaces as the unknowns. These integral equations are solved by the MoM to yield the surface currents. The radiation patterns of the two horns as well as the coupling between them are calculated from these surface currents. Numerical results are presented for a pair of axisymmetric horns.
