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. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2153–2158, 2014
