研究目的
To augment the Lebedev FDTD method for the simulation of electromagnetic waves in general dispersive anisotropic materials, allowing distinct dispersions to be applied to each of the principal axes of the anisotropic medium.
研究成果
The paper successfully introduces a new way to implement general dispersive anisotropic materials with distinct dispersions along each of the principal axes on the Lebedev grid. The method is simple to implement, with comparable memory requirements to existing methods, and demonstrates accuracy, validity, and stability through several examples.
研究不足
The method's complexity increases with the introduction of anisotropy and dispersion, requiring careful implementation to ensure stability and accuracy. The paper does not explicitly mention computational resource requirements, which could be a limitation for large-scale simulations.
