用传输矩阵法对含缺陷层的一维光子晶体的吸收特性进行了系统的研究。取介质层为非金属介质，缺陷层为金属介质，给出实际材料构成的光子晶体吸收率与波长的关系曲线，又对任意介质构成的光子晶体吸收特性进行了研究，即分别研究了入射角的变化、缺陷层折射率虚部的变化、介质层折射率的变化、介质层厚度的变化以及光子晶体周期结构的变化对光子晶体吸收特性的影响，得到了一些有价值的结论。通过调节光子晶体的一些参数，就可以发现这些参数对光子晶体吸收率的影响，从而为光子晶体的设计和制备提供了重要的理论依据。

The absorption property of one-dimensional photonic crystals with defect layer by the approach of transmission matrix is studied. In the photonic crystals, the medium layers are nonmetal, and the defect layer is metal. The relationship between absorption of real material and wavelength is given out, and then the absorption property of the photonic crystals is studied systematically, which is made up of arbitrary material. The effects of the incident angle, the refractive index of defect layer, the refractive index of medium layer, the thickness of medium layer and the periodic structure on the absorption property in the one-dimensional photonic crystals are given. Some valuable results are obtained. By adjusting the parameters of the photonic crystal, the affect of these parameters on the absorption property of the photonic crystals is found, which provides important theoretical basis for the design and preparation of photonic crystals.
