Two-dimensional materials are substances with a thickness of a few nanometres or less. Electrons in these materials are free to move in the two-dimensional plane, but their restricted motion in the ...
Abstract: The conventional Yee grid modeling approach employed within the unconditionally stable complying-divergence implicit finite-difference time-domain (CDI-FDTD) technique commonly encounters ...
Abstract: A relaxed modified FDTD (2,4) scheme (RM24) is proposed to alleviate the Courant condition. Extending the Modified FDTD (2,4) (M24) scheme, we incorporate third-degree spatial difference ...
