  • Abstract
    Late time instabilities are always present when applying the FDTD method in general curvilinear coordinates. In this paper, the stability analysis is performed on local nonorthogonal FDTD (LNFDTD) and a novel time-subgridding scheme is developed to reduce instabilities so that the full characteristics of electromagnetic structures can be explored.
