Abstract

The unconditionally stable Laguerre-FDTD method is suitable for simulating 3-D multi-scale structures. In this work, a new meshing scheme for treating material cell in Laguerre- FDTD method is proposed to improve the simulation accuracy. This scheme uses linear average calculation of effective material property at edges of a material cell. Numerical results show that the proposed algorithm achieves significant improvement in simulation accuracy over conventional meshing.
