โœฆ Synopsis


Diagonalization of the 3-D goยจerning equations, transยจerse field construction, field dependence on the perpendicular coordinate, fields within annuli, compact recursion equations in matrix form, and 3-D EH and HH dyadic Green's function elements are treated. Explicit dependence on substrate thickness is giยจen. Magnetic walls are imposed for nonport contour regions.

Imperfect walls at the deยจice perimeter are allowed. A new dyadic Green's function is found by specification of the source as a finite-length singularity in the z direction on the deยจice boundary contour at location ะˆ and the use of mode matching.

The EH Green's function is deriยจed under three circulator conditions, three-, four-, and six-fold geometric symmetry, from the general arbitrarily placed ports expression for inhomogeneous ferrite loading. Using these Green's functions, the multiport s-parameters and electric field are found. A larg
