Introduction to the Finite-Difference Time-Domain (FDTD) Technique

2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI), 2017
Strengths & Weaknesses of FDTD • Strengths — Time Domain Solution Provides Wide Frequency Range With One Run — All Materials Possible — Animation Provides Insight — Well Suited to Inside / Outside Problems (Shielding) — Intuitive Technique • Weaknesses — All Space Must Be Gridded • Memory Limitations — Far-Field Usually Requires Post-Processing ...

Finite-difference time-domain of HF antennas

Proceedings of MILCOM '94, 2002
Although there has been extensive research and application of the finite-difference time-domain (FDTD) method to electromagnetic scattering and penetration problems, only recently has FDTD been used to predict the radiation characteristics of antennas. The FDTD method has not been applied to low frequency or electrically small radiating structures. The

The symplectic finite difference time domain method

IEEE Transactions on Magnetics, 2001
A new method for solving Maxwell equations in the time domain, called the symplectic FDTD method, is formulated, discretized, implemented, and verified. This method preserves the symplecticness (preservation of area in the phase space, i.e., preservation of energy or helicity), improves the accuracy of the solution to the high frequency problem, and ...

Finite-Difference Time-Domain Methods for Electrodynamics

2020
The FDTD method belongs in the general class of grid-based differential numerical modeling methods (finite-difference methods). The time-dependent Maxwell’s equations (in partial differential form) are discretized using central-difference approximations to the space and time partial derivatives.

Sparse Finite Difference Time Domain Method

IEEE Photonics Technology Letters, 2013
We propose a new electromagnetic simulation method called the sparse finite difference time domain (FDTD) method. It is based on standard FDTD but is faster by approximately an order of magnitude for large waveguide circuits, because it calculates only where significant electromagnetic energy is present. We derive and demonstrate 2-D sparse FDTD.

Finite-difference time-domain diakoptic strategies

CEM'11 Computational Electromagnetics International Workshop, 2011
In many applications, it may be advisable to "tear apart" the computational domain into several sub-domains separated by "seams," each one treated separately. The sub-domains are then sewn back together at appropriate stages of the computation. We present three main diakoptic strategies, as described below.
