A Stable SBP-SAT FDTD Subgridding Method Without Region Split
Yuhui Wang, Langran Deng, Weibo Wu +7
A provably stable summation-by-parts simultaneous approximation term (SBP-SAT) finite-difference time-domain (FDTD) subgridding method without region split is proposed. By designin…
Spatio-Sequential Recurrent Network for 3-D Tunnel Propagation Modeling
Jiahao Li, Jingxin Xue, Keqi Ni +4
Fine-mesh parabolic wave equation (PWE) simulations are high-fidelity but time-consuming, which limits real-time tunnel propagation analysis and motivates coarse-to-fine reconstruc…
