Abstract

We present a fast method for solving low-frequency complex problems over a frequency band. In this method, we apply fast multipole method to accelerate the solution process of augmented electric field integral equation with perturbation method (enhanced A-EFIE). As the current is expanded as a power series in frequency in enhanced A-EFIE, results over a frequency band can be obtained by one low-cost simulation. Real circuit problem with one million unknowns is used to demonstrate the effectiveness of the method.
