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 ...

A standard cell hardware implementation for finite-difference time domain (FDTD) calculation

IEEE MTT-S International Microwave Symposium Digest, 2003, 2003
Several inherent characteristics make the Finite-Difference Time Domain (FDTD) algorithm almost ideal for the analysis of a wide class of microwave and high-frequency circuits as testified by the great number of papers that appeared in the last two decades and by the presence of many software packages on the present market.

Finite-difference time-domain (FDTD) analysis of magnetic diffusion

IEEE Transactions on Electromagnetic Compatibility, 1994
Problems with very slow waveforms or very long diffusion times may be difficult to treat using finite-difference time-domain techniques because of the Courant stability condition. Problems of this class, however, often prove to have a response which does not depend on the speed of light.

MR/FDTD: A multiple-region finite-difference--time-domain method

Microwave and Optical Technology Letters, 1997
Multiple-region FDTD (MR/FDTD), an extension of classical FDTD to multiple subregions within a problem domain, is introduced. In MR/FDTD the problem domain is broken into several independent FDTD subregion lattices. The subregions lattices are terminated with the use of a surface integrated radiation boundary condition applied simultaneously to all ...

Conformal finite difference time-domain (FDTD) for modeling frequency selective surface

2013 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference, 2013
Conformal finite-difference time-domain (CFDTD) is used for solving frequency selective surface in this paper. This approach is easy to implement and is numerically stable. Some models are simulated to demonstrate the accuracy and fast computation time of CFDTD.

Finite-Difference Time-Domain (FDTD) Analysis of Nonlinear Optical Waveguiding Devices

Integrated Photonics Research, 1995
In this work we have developed the theory required for a nonlinear FDTD simulator, including the propagator, the implementation of the nonlinearity, boundary and stability conditions, and source get eration. We validated the simulator by reproducing the published results for a self-guiding structure [1] and for a nonlinear directional coupler [2].

Finite Difference Time Domain (FDTD) Characterization of a Single Mode Applicator

Journal of Microwave Power and Electromagnetic Energy, 2003
Microwave heating plays an important role in the processing & heating of foods in the food industry and at home, but the applicator design is frequently an arduous task. Thefinite-difference time-domain (FDTD) method can be used to model complex geometries and guide the design of different types of applicators.

Modeling of periodic structures using the finite difference time domain (FDTD)

IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003
Two-dimensional planar periodic structures find many applications in practice because of their spatial filtering characteristics. A periodic array of conducting patch or aperture elements is often referred to as a frequency selective surface (FSS), or a dichroic filter.

A distributed implementation of the finite difference time‐domain (FDTD) method

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1995
AbstractThe finite difference time‐domain (FDTD) method is a well known numerical technique that has been used to solve electromagnetic boundary value problems. However, the method requires large computational resources to solve a problem, restricting its use on sequential computers to small problems.This has led to the use of expensive supercomputers ...

Optical disk structure analysis with finite-difference time domain (FDTD) method

SPIE Proceedings, 2003
A method of high-density optical disk structure design using computational electromagnetic FDTD analysis is proposed. A staircase method is used to simulate the realistic sidewall geometrical structure of the land-groove of phase-change optical disk. The phase-change materials appear as different optical characteristics under irradiation of different ...
