SYMMETRY CONSIDERATIONS BASED UPON 2-D EH DYADIC GREENS-FUNCTIONS FORINHOMOGENEOUS MICROSTRIP FERRITE CIRCULATORS

The EH Green's function is derived under three circulator conditions, three-, four-, and six-fold geometric symmetry, from the general arbit rarily placed ports expression for inhomogeneous ferrite lending. Usin g these Green's functions, the multiport s-parameters and electric fie ld are found. A large reduction in the number of Green's function elem ents which must be evaluated occurs.
