Abstract
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 λ/h (grid spacings per wavelength)=8, one achieves the same accuracy as the standard Yee algorithm does at λ/h=1140. In addition, greater algorithmic stability allows a reduction in the number of iterations needed to solve a problem
