Abstract :
The nonstandard finite difference time domain (NS-FDTD) method is a new high-accuracy FDTD method, but until now, it was applicable only at a single frequency. In this paper, we extend the NS-FDTD method to handle multiple frequencies in one computer run. We apply our new method to analyze the scattering analysis of a large cavity.
