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…

An Unconditionally Stable Conformal LOD-FDTD Method For Curved PEC Objects and Its Application to EMC Problems
Hanhong Liu, Xiaoying Zhao, Xiang-Hua Wang +3
The traditional finite-difference time-domain (FDTD) method is constrained by the Courant-Friedrich-Levy (CFL) condition and suffers from the notorious staircase error in electroma…
