Abstract :
It has been shown recently that the conventional stability limit of the Finite-Difference Time-Domain (FDTD) method can be extended via spatial filtering. The trade-off is the computational overhead of spatial filtering, which is even heavier in 3D. This paper accelerates the spatial filtering technique and further develope a late-time stable 3D spatially-filtered subgridding scheme.
