摘　　要：采用干涉矩阵方法对一维金属-介质光子晶体的光谱结构进行了研究。结果表明介质材料的厚度、折射率以及金属材料折射率的虚部对光子晶体光谱的影响可以采用驻波理论较好解释。当金属材料的厚度大于其趋肤深度时,厚度的增加会导致光子晶体的透射率和吸收率均降低,但对光子晶体透射和吸收峰的位置没有影响。The spectral structure of the one-dimensional metallodielectric photonic crystal is studied. The result shows that the theory about stationary wave can be used to properly explain the relationship between the spectral structure and the thickness of the dielectric material, the index of refraction of the dielectric and metallic materials composed photonic crystal. And the thicker of the metallic material deeper than the skin depth will lead to a lower transmittance and absorption,but the thickness do not affect the position of the peak of transmittance and absorption.
