详细介绍了一种新的有效率的FDFD方法，通过将电场、磁场分开成两个矩阵方程，达到高效的目的。

对计算光子晶体光纤基模的总结，希望对大家有所帮助。-Photonic crystal fiber modes analysis using finite-difference time-domain method and finite-difference frequency-domain method

频率域有限体积波场模拟，可用于三角形不规则网格，较有限差分速度更快。-Frequency domain finite volume wave field simulation can be used for irregular triangular grid, faster than the finite difference.
