Towards the Development of A Three-Dimensional SBP-SAT FDTD Method: Theory and Validation

Yu Cheng, Hanhong Liu, Xinsong Wang +5

To enhance the scalability and performance of the traditional finite-difference time-domain (FDTD) methods, a three-dimensional summation-by-parts simultaneous approximation term (…

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…

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…

Investigation of Numerical Dispersion with Time Step of The FDTD Methods: Avoiding Erroneous Conclusions

Yu Cheng, Guangzhi Chen, Xiang-Hua Wang +1

It is widely thought that small time steps lead to small numerical errors in the finite-difference time-domain (FDTD) simulations. In this paper, we investigated how time steps imp…
