Seismic Numerical Simulation Based on Half-precision Floating-point Number Optimization and OpenMP
Studying the propagation law of seismic wavefields is the basis of seismic exploration. The finite difference method is commonly used to solve the wave equation for seismic forward modeling, which has advantages of low memory usage, fast computation ...

From Time-Collocated to Leapfrog Fundamental Schemes for ADI and CDI FDTD Methods
The leapfrog schemes have been developed for unconditionally stable alternating-direction implicit (ADI) finite-difference time-domain (FDTD) method, and recently the complying-divergence implicit (CDI) FDTD method.

1D Quantum Simulations of Electron Rescattering with Metallic Nanoblades
Electron rescattering has been well studied and simulated for cases with ponderomotive energies of the quasi-free electrons, derived from laser−gas and laser−surface interactions, lower than 50 eV.

Optimizing FDTD Memory Bandwidth by Using Block Float-Point Arithmetic
Finite-difference time-domain is a numerical method used for modelling of computational electrodynamics. The method is resource intensive, especially regarding memory usage. Multiple memory accesses are required per single computation so memory bandwidth

Electromagnetic analysis of complex 3D PEC structures using a stabilised CPFDTD algorithm [PDF]
It has been shown that, with a simple modification, the contour path FDTD (CPFDTD) scheme can be stabilised while still being accurate for structures with a complex geometry containing tilted planes, smooth curved surfaces and right-angle bends. This has

The treatment of thin wire and coaxial structures in lossless and lossy media in FDTD by the modification of assigned material parameters [PDF]
It has been shown recently that the use of modified assigned material parameters (MAMPs) within the finite-difference time-domain (FDTD) method provides a systematic, readily extensible, accurate, and efficient approach to the electromagnetic analysis of
