Abstract

A two dimensional (2-D) finite-difference time-domain (FDTD) method based on a novel finite difference scheme is developed to eliminate the numerical dispersion errors. In this paper, the numerical dispersion and stability analysis of the new scheme are given; these show that the proposed method is nearly dispersionless and stable for a larger time step than the standard FDTD method for a monochromatic frequency. The new algorithm is also verified for two cases.
