IMPLICIT 3-D DYADIC GREENS-FUNCTION FOR INHOMOGENEOUS FERRITE MICROSTRIP CIRCULATOR WITH UNIFORM SURROUNDING AND TOP MATERIAL USING MODE MATCHING

It is possible to combine the source constraint equations with the mod e-matching technique employing mode orthogonality to encourage sparsit y in subsequent matrix system development, to obtain in direct space i mplicit dyadic Green's function elements. This is particularly useful because field information and s-parameters may be found in real space completely avoiding typical inverse transformations. The approach allo ws the inclusion of uniform surrounding dielectric material as well as a cover plate above the ferrite puck. (C) 1998 John Wiley & Sons, In c.
