摘要：

New nonstandard second-order finite differences (FD's) are introduced, which when substituted into the Yee algorithm, reduce the solution error 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, greater algorithmic stability allows a reduction in the number of iterations needed to solve a problem.
