Cm. Krowne, 3-D THEORY FOR A RADIALLY INHOMOGENEOUS MICROSTRIP CIRCULAR FERRITE CIRCULATOR UTILIZING A RECURSIVE DYADIC GREENS-FUNCTION, Microwave and optical technology letters, 18(3), 1998, pp. 219-227
Diagonalization of the 3-D governing equations, transverse field const
ruction, field dependence on the perpendicular coordinate, fields with
in annuli, compact recursion equations in matrix form, and 3-D EH and
HH dyadic Green's function elements are treated. Explicit dependence o
n substrate thickness is given. Magnetic walls are imposed for nonport
contour regions. (C) 1998 John Wiley & Sons, Inc.
