Abstract
New nonstandard second-order finite differences (FD's) are introduced, which when substituted into the Yee algorithm, reduce the solution er ror by a factor of 10(-4) on a coarse computational grid, Using lambda /h (grid spacings per wavelength) = 8, one achieves the same accuracy as the standard Yee algorithm does at lambda/h = 1140, In addition, gr eater algorithmic stability allows a reduction in the number of iterat ions needed to solve a problem.
