The efficient computation of intrinsic frequencies of resonators is presented by an FDTD computation using a new excitation function and a subsequent application of Prony's method. For an accurate extraction of the frequencies, the excitation function must be rather short in the time domain, as well as having a well‐defined frequency content. A sinc‐type excitation function allows very short simulation times, as well as convenient computation near the Courant limit. The sampling of Prony's method starts after the excitation has decayed, a point in time well defined with the new excitation. © 2001 John Wiley & Sons, Inc.
