Application of FPGA technology to accelerate the finite-difference time-domain (FDTD) method

Proceedings of the 2002 ACM/SIGDA tenth international symposium on Field-programmable gate arrays - FPGA '02, 2002
The continuing advances in the field of electrical engineering, in areas like cellular communications, fiber optics, mobile and multi-gigahertz electronics have necessitated a computer-assisted design approach to the complex electromagnetic interactions and problems that arise.

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.

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.

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.

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.

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.

Modeling of near-field sources in the finite-difference time-domain (FDTD)

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
A method is outlined to represent near-field sources in the FDTD method by way of spherical wave expansions. Spherical wave modal amplitude functions are time-stepped on alternate 1-dimensional grids (in radius and time) analogous to plane waves in the total/scattered field formulation, with angular functions interpolated later.

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 ...

Finite Difference Time Domain (FDTD) Simulations Using Graphics Processors

2007 DoD High Performance Computing Modernization Program Users Group Conference, 2007
This paper presents a graphics processor based implementation of the Finite Difference Time Domain (FDTD), which uses a central finite differencing scheme for solving Maxwell's equations for electromagnetics. FDTD simulations can be very computationally expensive and require thousands of CPU hours to solve on traditional general purpose processors ...

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
