wgms3d一个全矢量电磁波导模式求解。它在指定的计算采用二阶有限差分法波长介质波导的模式。波导截面可以由不断折射率几个相邻的地区。介电接口不必与离散网格对齐，他们可以任意倾斜或弯曲。整个波导可弯曲沿传播方向。泄漏和曲率损失可以计算用完全匹配层吸收边界。
wgms3d 1.1.0更新说明：
Added support for lossy materials. Inside the geometry (.mgp) file, you may now either specify the refractive index as a single real number (as before), or as a pair of the form (nr,ni), where nr and ni are the real and imaginary parts of the refractive index. For an example, see the new tests/lossy_materials/ test script. Added new Matlab script, matlab/wgms3d_mgp_rib_waveguide.m, for generating rib waveguide structures. Added new Matlab script, matlab/wgms3d_calc_group_index.m, that calculates the group index of a mode from its field distribution (only for non-dispersive materials). No longer
exporting epsis.txt with the -e switch, but epsis.bin instead. Added missing script matlab/wgms3d_tracemodes_update_">parameter.m.
