摘要

An efficient 2D locally one-dimensional finite-difference time-domain (LOD-FDTD) method in lossy material is presented in this Letter. The weighted factor and scaling factors of the isotropic dispersion FDTD method are reformed for the LOD-FDTD method in lossy media. Compared with the conventional LOD-FDTD method, the relative attenuation and phase errors of the proposed method are significantly reduced. The numerical anisotropy is also greatly improved by using the proposed method.
