A SBP-SAT FDTD Subgridding Method Using Staggered Yee's Grids Without Modifying Field Components
Yuhui Wang, Yu Cheng, Xiang-Hua Wang +2
A summation-by-parts simultaneous approximation term (SBP-SAT) finite-difference time-domain (FDTD) subgridding method is proposed to model geometrically fine structures in this pa…

A Stable FDTD Subgridding Scheme with SBP-SAT for Transient Electromagnetic Analysis
Yu Cheng, Yuhui Wang, Hanhong Liu +5
We proposed a provably stable FDTD subgridding method for accurate and efficient transient electromagnetic analysis. In the proposed method, several field components are properly a…
