Abstract :
A structured nonorthogonal finite-difference time-domain (FDTD) method incorporating existing perturbation techniques is used to determine the Q factor of an arbitrary three-dimensional cavity resonator. The new scheme combines the efficiency of the Cartesian mesh with the accuracy of the conformal grid. Good results are achieved with little computational effort
