Conformal hybrid finite difference time domain and finite volume time domain
IEEE Transactions on Antennas and Propagation, 1994A hybrid method that combines the finite difference time domain (FDTD) and the finite volume time domain (FVTD) methods is presented. The FVTD, based on a conformal and unstructured grid is used in the near vicinity of the surface of a scatterer, and the FDTD is used to model the fields in the surrounding area.

On the Stability of the Finite-Difference Time-Domain Method
Journal of Computational Physics, 2000The finite difference time domain method used for solving transient electromagnetic fields is studied. Maxwell equations are introduced, normalized and written in terms of an iteration matrix form. The eigenvalue problem for this matrix is analysed. From this analysis a necessary and sufficient conditon for the finite-difference time domain method is ...

The Finite-Difference Time-Domain Method
1998The Finite-Difference Time-Domain (FDTD) method provides a direct integration of Maxwell’s time-dependent equations. During the past decade, the FDTD method has gained prominence amongst numerical techniques used in electromagnetic analysis. Its primary appeal is its remarkable simplicity.

Least Squares Finite-Difference Time-Domain
IEEE Transactions on Antennas and Propagation, 2021A central least-squares spatial derivative procedure is developed. It provides simple formulas, similar to finite differences, to approximate spatial derivatives. In addition, a least-squares finite-difference time-domain (LS-FDTD) method is formulated for attenuating high-frequency nonphysical modes, superimposed to physical solution, produced by Yee ...

Finite-difference time-domain on the cell/B.E. processor
2008 IEEE International Symposium on Parallel and Distributed Processing, 2008Finite-Difference Time-Domain (FDTD) is a kernel used to solve problems in electromagnetics applications such as microwave tomography. It is a data-intensive and computation-intensive problem. However, its computation scheme indicates that an architecture with SIMD support has the potential to bring performance improvement over traditional ...

Finite difference time domain methods for piezoelectric crystals
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2006The numerical simulation of acoustic wave propagation through piezoelectric crystals using the finite-difference time-domain (FDTD) method is introduced. The update equations for the velocity and stress fields are derived and applied to the propagation of ultrasonic waves in three substrates.

Finite-Difference Time-Domain Methods
2005Publisher Summary This chapter discusses finite-difference time-domain (FDTD) methods. During the 1970s and 1980s, a number of researchers realized the limitations of frequency-domain integral-equation solutions of Maxwell's equations. This led to early explorations of a novel alternative approach: direct time-domain solutions of Maxwell's ...
