| Research Abstract |
The body-of-revolution finite-difference time-domain method based on the locally one-dimensional scheme (LOD-BOR-FDTD) has been developed for the efficient analysis of circularly symmetric structures. In particular, the general formulation is presented in order to treat higher-order modes with respect to the rotational direction. As a result, the computational time is reduced to only 28% of that of the conventional explicit method for the analysis of resonance frequencies of higher-order modes for a circular cavity resonator. In addition, the LOD-FDTD method is extended to a three-dimensional (3-D) version. Furthermore, a frequency-dependent 3-D LOD-FDTD method is developed to analyze plasmonic devices.
