Ferrite analysis using the finite‐difference time‐domain (FDTD) method

Microwave and Optical Technology Letters, 1992
AbstractThis article introduces a new method for analyzing ferrite structures. This method is implemented in a FDTD algorithm; then the computation is directly made in the time domain. An application in the particular case of a two‐dimensional problem is presented.

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 ...

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 ...

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

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.

Tutorial on finite-difference time-domain (FDTD) methods for room acoustics simulation

The Journal of the Acoustical Society of America, 2021
Wave-based simulation models for acoustics have remained an active area of research and development for the past three decades. Wave-based methods aim to solve the 3D wave equation directly and therefore have large computational costs relative to conventional ray-based methods, which tend to simplify wave-diffraction effects.
