y solving Helmholtz wave equations numerically, the absorption, reflection and transmission of a plasma layer with different scale-lengths and thicknesses varying with incident angles and polarizations are studied.

• 通过数值求解亥姆霍兹（Helmloltz）波动方程，研究了激光辐照薄膜靶产生的不同厚度、不同标尺长度的薄层等离子体对激光的反射、透射及吸收（逆轫致吸收，共振吸收）率随入射角的变化情况。
