Abstract :
An efficient methodology for the accurate calculation of closed-form Green´s function in multilayered planar media is combined with the adaptive integral method (AIM) to provide a fast, iterative, full-wave solver for the analysis of complex planar integrated circuits. The computational complexity per iteration and memory requirements for the AIM-based electromagnetic solver scale as O(N log N) and O(N), respectively, where N is the number of unknowns in the discrete model. The accuracy and efficiency of the solver is demonstrated through its application to the modeling of an integrated, planar circuit component.
