Abstract
This paper investigates the characteristics of evanescent waves in the nonstandard finite difference time domain (NS-FDTD) method and derives the dispersion equation for two-dimensional space. The validity of the dispersion equation is confirmed by comparison with results of numerical simulations. It is shown that the NS-FDTD method has highly accurate characteristics not only for propagating waves, but also for evanescent waves compared with the standard FDTD method
