AB - In this paper, a practical implementation of the spatial
images technique for the analysis of shielded multilayered printed
circuits inside convex cavities is proposed. A new method is introduced
in order to automatically locate the images surrounding the
structure in order to impose the appropriate boundary conditions
for the potentials. The boundary conditions are imposed at discrete
points along the cavity wall and, therefore, the technique proposed
is an approximation to the exact cavity modeling. Furthermore,
for the analysis of electrically long cavities, the use of several
rings of images surrounding the entire cavity at different heights
is employed. Using the special features of the formulation, a new
method of moments implementation combined with the spatial images
technique is proposed in order to efficiently analyze practical
multilayered printed filters, considerably reducing the computational
cost. Several examples with CPU time comparisons are provided,
demonstrating the accuracy and efficiency of the new technique.
A novel transversal filter in a trapezium-shaped cavity is
designed, manufactured, and tested for the first time using the spatial
images technique.
