A Three-Dimensional Angle-Optimized Finite-Difference Time-Domain Algorithm
We present a three-dimensional finite-difference time-domain (FDTD) algorithm to minimize the numerical dispersion error at preassigned angles. Filtering schemes are used to further optimize its frequency response for broad-band simulations. A stability analysis of the resulting FDTD algorithm is also provided. Numerical results show that the dispersion error around any preassigned angle can be...
متن کاملThree-dimensional Finite Difference-Time Domain Solution of Dirac Equation
The Dirac equation is solved using three-dimensional Finite DifferenceTime Domain (FDTD) method. Zitterbewegung and the dynamics of a well-localized electron are used as examples of FDTD application to the case of free electrons.

متن کاملGPU Accelerated 2-D Staggered-grid Finite Difference Seismic Modelling
The staggered-grid finite difference (FD) method demands significantly computational capability and is inefficient for seismic wave modelling in 2-D viscoelastic media on a single PC. To improve computation speedup, a graphic processing units (GPUs) accelerated method was proposed, for modern GPUs have now become ubiquitous in desktop computers and offer an excellent cost-toperformance-ratio pa...

15 صفحه اولSeismic modeling by optimizing regularized staggered-grid finite-difference operators using a time-space-domain dispersion-relationship-preserving method
The staggered-grid finite-difference (FD) method is widely used in numerical simulation of the wave equation. With stability conditions, grid dispersion often exists because of the discretization of the time and the spatial derivatives in thewave equation. Therefore, suppressing grid dispersion is a key problem for the staggered-grid FD schemes. To reduce the grid dispersion, the traditional me...
