摘要

Sub-gridding errors for a 2D Finite-DifferenceTime-Domain (FDTD) simulation are compared for both thestandard FDTD and Hybrid higher order FDTD cases. Subgriddingcontrast ratios of 1:3, 1:9, 1:15, and 1:27 are consideredand analyzed. A correlation is seen between the increase ofcontrast ratio with the increase of sub-gridding errors for bothstandard and hybrid cases. However, a trend of errors reductionwhen using hybrid formulations over standard formulations isapparent for each contrast ratio.
