This paper presents a new combination of the 3D alternating‐direction implicit finite‐difference time‐domain (ADI‐FDTD) method and the modified matrix pencil (MMP) method for the efficient calculation of microwave integrated circuits. It is demonstrated that the time step in the ADI‐FDTD algorithm can be four times greater than that of the conventional FDTD without a large loss of accuracy. The MMP method can be used to further reduce the computational time by more than 60% with a reasonable accuracy comparable to that obtained using the ADI‐FDTD method in the frequency domain. The iteration number of the ADI‐FDTD algorithm combined with the MMP method can be 12 times less than that of the conventional FDTD method for the analysis of microstrip circuits. © 2005 Wiley Periodicals, Inc.
