Abstract :
An efficient algorithm combining the adaptive integral method and the discrete complex image method is presented for analyzing large-scale microstrip structures. The mixed potential integral equation is discretized using the RWG basis functions for expansion and testing. The biconjugate gradient method is employed to solve the resulting matrix equation. The resulting algorithm has the memory requirement proportional to O(N) and the operation count for the matrix-vector multiplication proportional to O(Nlog N). Numerical results for some microstrip circuits and a microstrip antenna array are presented to demonstrate the efficiency and accuracy of this method
