Abstract
The authors present a novel surface integral equation approach to analyse inductive
microwave devices with several parallel input output ports containing inductive metallic and
dielectric obstacles. The technique decomposes the main problem into three subproblems, employ-
ing different kinds of Green's functions. One of the subproblems uses the classical Green's func-
tions of an infinite unbounded medium with the constitutive parameters of the dielectric obstacles.
A novel point of the technique is the formulation of the two other subproblems with two different,
908 rotated parallel plate regions. In these regions the parallel plate waveguide Green's functions
are used to simplify the modelling of the excitation problem. The second novel aspect of the work is
in the treatment of these Green's functions, to smooth their behaviour, and to improve their con-
vergence. Several numerical results are presented to demonstrate the usefulness of the algorithms
proposed. Also, several ...
