In this paper, a simple and computationally low-cost modification of the standard finite-difference time-domain (FDTD) algorithm is presented to reduce numerical dispersion in the algorithm. Both twoand three-dimensional cases are considered. It is shown that the maximum error in phase velocity can be reduced by a factor of 2–7, depending on the shape of the FDTD cell. Although the reduction procedure is optimal for only single frequency, numerical examples show that the proposed method can… CONTINUE READING
