A novel technique for an efficient analysis of microwave circuits etched in layered media

In this paper, a novel technique for efficient electromagnetic simulation of microstrip circuits etched in layered media is presented. The proposed approach is useful for rapid prototyping of the desired circuit response and it uses closed-form expressions for the evaluation of the fields radiated by rooftop basis functions, applied in conjunction with an algorithm referred to herein as the Equivalent Medium Approach. Illustrative examples demostrating the reliability and the efficiency of the described procedures are included.
