In this article, the authors extended the hybrid implicit-explicit finite-difference time domain (HIE-FDTD) scheme for a 2D transverse electric (TE) wave to a full 3D electromagnetic wave.Abstract:
The hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) scheme for a 2-D transverse electric (TE) wave is extended to a full 3-D electromagnetic wave in this paper. With the weakly conditional stability, this approach simulates shielding effectiveness of an enclosure with high computation efficiency. Numerical formulations of the 3-D HIE-FDTD scheme are presented, and simulation results are compared to those obtained by using the conventional 3-D FDTD and alternating-direction implicit (ADI) FDTD methods. The accuracy and efficiency of the 3-D HIE-FDTD for prediction of shielding effectiveness are validated by numerical simulation results.read more

A Novel 3-D HIE-FDTD Method With One-Step Leapfrog Scheme
TL;DR: In this article, a 3D leapfrog hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) method was proposed, in which the implicit scheme was applied only in the direction where a fine grid was applied and the explicit schemes were applied in two other directions where a larger grid was used.

Numerical solution of initial boundary value problems involving maxwell's equations in isotropic media
Abstract: Maxwell's equations are replaced by a set of finite difference equations. It is shown that if one chooses the field points appropriately, the set of finite difference equations is applicable for a boundary condition involving perfectly conducting surfaces. An example is given of the scattering of an electromagnetic pulse by a perfectly conducting cylinder.
