Resumen
The use of ground planes is proposed inside the
spatial images technique in order to calculate the multilayered
shielded Green's functions for rectangular enclosures. The positions of the ground planes are dynamically located, covering
two walls of the cavity, as a function of the source position.
Spatial mirror images, related to the ground planes, are used to
perfectly impose the boundary conditions along these cavity walls.
This completely removes the problems associated to the singular
behavior of the source when it is placed close to a wall or a
corner, improving numerical stability. In addition, the method
leads to a very efficient computation (about 15 times faster than
the original approach), due to the reduced number of non-mirror
images that must be effectively computed. A multi-band filter in
hybrid waveguide-microstrip technology is analyzed with the new
method, showing excellent agreement with measured data.
