%X An efﬁcient calculation of the Green’s functions inside multilayered shielded cavities with right
isosceles-triangular cross-section is presented. The method is entirely developed in the spatial domain, and it
is based on image theory. The idea is to use the spatial-domain Green’s functions inside a multilayered
shielded square box, in order to accurately obtain the Green’s functions for the right isosceles-triangular
cavity. Image theory is then used to enforce the boundary conditions along the non-equal side of the triangle.
It is shown that the new algorithm is very robust, with limited computational effort. Resonance frequencies
and potential patterns of a triangular cavity have been calculated and compared with those obtained by other
techniques, showing very good agreement. Finally, a transversal ﬁlter inside a multilayered triangular-shaped
cavity is designed, manufactured and tested using the developed technique.
