Exciting electronic characteristics emerge when scientists stack 2D materials on top of each other and give the top layer a little twist. The twist turns a normal material into a patterned lattice and ...
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 ...
