✦ Synopsis

The unloaded Q of complex cavity structures is computed by using the finite-difference-time-domain technique (FDTD). The FDTD technique computes the cavity fields that are integrated in time and space to yield the stored energy and power loss frvm which the quality factor is obtained.

A comparison of the Q computed from this method with analytical and measured results is given.
