Abstract
A continuous counterpart of the spatial images technique is proposed for the computation of the multilayered boxed
Green's functions and their derivatives. The method employs a
set of auxiliary linear distribution of sources to effectively impose
the potential boundary conditions along the whole cavity contour.
The imposition of these boundary conditions leads to a set of integral equations (IEs), on the unknown distributions of the auxiliary sources, which are solved by applying a method of moments
approach. A convergence/efficiency study, related to the test and
basis functions choice, is then presented and discussed. The tech-
nique is combined with the use of dynamic ground planes generating mirror basis functions, which completely remove any singular instability. Finally, the computed Green's functions are included into a mixed-potential IE formulation for the accurate and
very fast analysis of practical multilayered shielded circuits. The
proposed technique does not suffer ...
