The finite-difference time-domain (FDTD) method is a widespread numerical tool for full-
wave analysis of electromagnetic fields in complex media and for detailed geometries …

Meshless methods are a promising new field in computational electromagnetics. Instead of
relying on an explicit mesh topology, a numerical solution is computed on an unstructured …

In this paper, an explicit and unconditionally stable finite-difference time-domain (FDTD)
method is developed for electromagnetic analysis. Its time step is not restricted by the space …

The root cause of the instability is quantitatively identified for the explicit time-domain finite-
element method that employs a time step beyond that allowed by the stability criterion. With …

A 3-D finite-difference time-domain (FDTD) scheme with controllable stability beyond the
stability limit of FDTD is presented. The key to controlling the FDTD stability limit is a spatial …

An alternative method is developed to make an explicit FDTD unconditionally stable. In this
method, given any time step, we find the modes that cannot be stably simulated by the given …

This paper presents an efficient 3-D finite-difference time-domain (FDTD) subgridding
scheme that is free of the Courant-Friedrichs-Lewy stability condition, for the modeling of …

The time step and grid spacing in explicit finite-difference (FD) modeling are constrained by
the Courant-Friedrichs-Lewy (CFL) condition. Recently, it has been found that the spatial FD …

The explicit finite-difference scheme is widely used for solving the wave equation; however,
its time step is strictly constrained by the Courant-Friedrichs-Lewy (CFL) stability limit. We …

This paper presents a new approach for modeling of electrically thin conductive shields in
the finite-difference time-domain (FDTD) method. The method is based on representation of …
