Cálculo eficiente de la función de Green en cavidades multicapa con sección transversal de tipo triángulo rectángulo-isósceles

Abstract

In this paper, 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 Green’s functions inside a multilayered shielded square box in order to accurately obtain the Green’s functions of the triangular structure. It is shown that the new algorithm is very robust, with limited computational effort. Cut-off frequencies and potential patterns of a triangular cavity have been calculated and compared to those obtain 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.
