• LOD-FDTD
• numerical dispersion
• compact higher-order
• parameter optimization

A two-dimensional (2D) locally one-dimensional finite-difference time-domain (LOD-FDTD) method with low numerical dispersion is introduced by virtue of a parameter-optimized compact fourth-order scheme. The numerical dispersion error and anisotropy of numerical phase velocity of this new method are proven to be significantly reduced compared with the original second-order method.
