Abstract
This paper presents an efficient technique for the analysis of arbitrary shaped circuits and antennas when embedded in metal-lic cavities. The technique uses the integral equation formulation and is based on the repre-sentation of the rigorous spatial domain boxed Green’s functions in terms of modal series ex-pansions. A new analytical integration scheme extended to arbitrary triangular domains is de-rived and asymptotic extraction procedures are used to enhance the convergence of the integral equation kernel. The technique thus derived is very efficient computationally and the simulated results show good agreement with measurements.
