Abstract: In this paper, we propose a new 3-D conservative FDTD(2, 4) scheme exhibiting properties close to the 2-D-M24 scheme. This scheme is designed to retain a 2-D stencil in the field update equations and has high-phase accuracy at low-grid resolutions. Moreover, an accurate Courant–Friedrichs–Lewy condition has been validated for this scheme. Some experiments are conducted to assess the higher accuracy of the proposed scheme.
