A new hybrid implicit-explicit FDTD method for local subgridding in multiscale 2-D TE scattering problems [PDF]

, 2016
The conventional finite-difference time-domain (FDTD) method with staggered Yee scheme does not easily allow including thin material layers, especially so if these layers are highly conductive.

1D Quantum Simulations of Electron Rescattering with Metallic Nanoblades

Instruments, 2019
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

Elektronika ir Elektrotechnika, 2018
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
