为能将隧道薄膜与光存储分层媒质看成一个整体膜系分析固体浸没透镜的透过率,将Abeles的光波在介质分层媒质中的传播理论和分析方法扩展到了隧道薄膜。给出隧道薄膜的特性矩阵和透过率函数,分析出按隧道薄膜厚度指数增加的解的系数是该解倒数的平方,由此证明隧道薄膜中两个衰减方向相反的倏逝波都是电磁场方程的合理解。据此计算分析了两类用于近场光学存储的固体浸没透镜的透过率。结果说明,超半球齐明固体浸没透镜的透过率一般优于半球同心固体浸没透镜的透过率。
In order to analyze the transmittance of the tunneling film and the optical storage layered media as a whole film analysis of the solid immersion lens, the propagation theory and analysis method of Abeles’ light wave in the media layered media is extended to the tunneling film. The tunneling film’s characteristic matrix and transmittance function are given. It is analyzed that the coefficient of the tunneling film’s exponential increase is the square of the inverse of the tunneling tunnel. It is proved that the two evanescent waves in the tunneling film with opposite decay directions are all electromagnetic A reasonable solution to the equation. Based on this calculation, the transmittance of two types of solid immersion lenses for near-field optical storage is calculated and analyzed. The results show that the super hemisphere Qiming solid immersion lens transmittance is generally better than the hemisphere concentric solid immersion lens transmittance.
