DOI: 10.1049/el.2017.4539
Abstract: A 3D optimised hybrid implicit–explicit finite-difference time-domain (HIE-FDTD) method aimed at suppressing the numerical dispersion is proposed. Compared with the original HIE-FDTD method, the optimised parameters are introduced without costing any additional computational resource. In… read more here.

DOI: 10.1109/lawp.2021.3079560
Abstract: In order to analyze electromagnetic targets with fine structure in one direction more effectively and accurately, optimized 3-D hybrid implicit–explicit finite-difference time-domain (HIE-FDTD) algorithms are formulated based on isotropic dispersion (ID) finite difference (FD) schemes,… read more here.
