Custom hardware implementation of the finite-difference time-domain (FDTD) method

2002 IEEE MTT-S International Microwave Symposium Digest (Cat. No.02CH37278), 2003
Finite-Difference Time-Domain (FDTD) Analysis is a very popular method for solving electromagnetic problems. The algorithm is computationally Intensive and simulations can take several days to run on traditional, multiprocessor supercomputer platforms.

Parallel implementations of the finite difference time domain (FDTD) method

Second International Conference on Computation in Electromagnetics, 1994
In this paper different parallel and sequential implementations of the finite difference time domain (FDTD) method are evaluated. The performance of current sequential architectures are first investigated. Possible improved performances from different parallel architectures are then examined.

A novel separable backward-central finite difference time domain (FDTD) method

2005 IEEE Antennas and Propagation Society International Symposium, 2005
In this paper, we present a novel, separable, backward-central FDTD (SBC-FDTD) method in which both the backward and central differencing are employed to discretize the time and spatial derivatives of the Maxwell's equations. For the type of problems in which the FDTD cell size in one direction is much smaller than those along the other directions, the

Stability comparison between Multi-Resolution Time-Domain (MRTD) and Finite-Difference Time-Domain (FDTD) techniques

2008 Loughborough Antennas and Propagation Conference, 2008
The multi-resolution time-domain (MRTD) technique is a superior numerical algorithm over the long established finite difference time-domain (FDTD) technique. The advantages of low numerical dispersion and less memory intensive are particularly of interest for analyzing hybrid structures involving antennas and metamaterials.

Finite difference time domain (FDTD) analyses applied to NDT & E inductive sensor modelling

Communications in Numerical Methods in Engineering, 2007
AbstractIn this work, a simple but effective algorithm was developed that can perform 3D simulations of magnetic fields emanating from coils and simple geometry objects in the time‐harmonic domain. The software was intended to provide information that would help in an inductive sensor design, by simulating the interaction of the excitation field with ...

Appendix C. The finite-difference time-domain (FDTD) method

2018
The simulations used in this work were all done using the finite-difference timedomain (FDTD) method. One of a fairly large number of methods and variations on methods applicable to the simulation of electromagnetic fields, the FDTD is particularly simple and intuitive, and its application is well adapted to computation of high-frequency ...

Graphics processor unit (GPU) acceleration of finite-difference time-domain (FDTD) algorithm

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
The finite-difference time-domain (FDTD) algorithm has become a tool of choice in many areas of RF and microwave engineering and optics. However, FDTD runs too slow for some simulations to be practical, even when carried out on supercomputers. The development of dedicated hardware to accelerate FDTD computations has been investigated. In this paper, we

Finite-Difference Time-Domain (FDTD) Simulation of Microwave Sintering in Multimode Cavities

MRS Proceedings, 1992
ABSTRACTMicrowave sintering of ceramics in multimode cavities, particularly the use of picket-fence arrangements, has recently received considerable attention. Various types of ceramics have been successfully sintered and, in some cases, a desirable and unique “microwave effect” has been observed.At present, various aspects of the sintering process ...

Interfacing optical system software to finite-difference time-domain (FDTD) software

SPIE Proceedings, 2005
There has recently been an increased interest in being able to model optical systems that include sub-wavelength structures at one or more points in the system model. Software using the finite-difference, time-domain (FDTD) method can accurately model the interaction with the sub-wavelength structures, but cannot practically model the entire optical ...

Finite Difference Time Domain (Fdtd) Analysis of an Artificially-Synthesized Absorbing Medium

Journal of Electromagnetic Waves and Applications, 2001
In this paper, we investigate an artificially-synthesized absorbing medium by using the Finite Difference Time Domain (FDTD) technique. The artificial medium is composed of a doubly-periodic array of lossy electric and magnetic material blocks (i.e., μ and e media arranged in a checkerboard configuration).
