In this paper, we present a finite‐difference time‐domain technique for determining the resonance frequencies of microwave components by deriving the standing‐wave patterns rather than simulating the scattering parameter spectra of the component. We show that, compared to the S ‐parameter spectra simulation technique, the technique proposed herein can save the time needed to compute the resonant frequencies by an order of magnitude. © 2001 John Wiley & Sons, Inc.
