In this letter, a modified locally one-dimensional finite-difference time-domain (LOD-FDTD) method is proposed. The dispersion behavior is investigated and compared with the conventional LOD-FDTD method. It is found that for a Courant-Friedrich-Levy number equal to 5 the modified LOD-FDTD method performs approximately 20% better than the conventional LOD-FDTD method
