Efficient time-domain techniques for the wideband analysis of plasmonic antennas

We have introduced the TRC technique for the efficient FDTD analysis of plasmonic antennas. The TRC technique requires only a single convolution integral, while maintaining the same accuracy of the PLRC technique with two convolution integrals. The frequency-dependent LODFDTD has also been mentioned as a practical alternative to the explicit frequency-dependent FDTD. The LOD-FDTD enables us to use a large time step, which is expected to reduce the computation time for the analysis of plasmonic antennas.
