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…
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…
