    "abstract": "In this paper, we extend the conventional plane wave expansion method in 3D\nanisotropic photonic crystal to be able to calculate the complex $\\mathbf{k}$\neven if permittivity and permeability are complex numbers or the functions of\n$\\omega$. There are some tricks in the derivation process, so we show the\nprocess in detail. Besides, we also provide an example for testing and\nexplaining, and we also compare the results with the band structure derived\nfrom conventional plane wave expansion method, then we finally find that there\nis a good consistency between them.",
