shape distribution

With dielectric constant distribution function of Fourier coefficients as a foundation, we calculated the arbitrary shape two-dimensional photonic crystals' bandgap structures by PWM ( Plane Wave Expansion Method).

有了介电常数分布函数的傅立叶展开系数做基础，用平面波展开法计算了任意形状二维介质光子晶体的带隙结构，求解带结构的主要方法是通过计算本征方程的特征根。

The spectrally noncritical phase-matching SHG in the pump depletion regime is researched. The influence of reconversion and third-order nonlinearity on the conversion efficiency, as well as on pulse shape and spectral distribution is analyzed theoretically.
