论文摘要
经典电磁边界条件（EMBC）无法描述纳米级的量子界面现象。在这里，我们使用一个过渡层构建了界面模型，该过渡层描述了界面上电磁场的不均匀性。通过引入磁界面响应函数（IRF）来得出广义的纳米级胚胎，并根据麦克斯韦方程在一阶近似中根据麦克斯韦方程重写三种不同的形式。相应的菲涅尔公式被进一步用于分析界面光子现象，表明布鲁斯特角移动的有趣行为，在布鲁斯特角度不伸入，在布鲁斯特角度和布鲁斯特角度的独特非经典吸收或增益效应以及总内部反射角。 Brewster角度附近的高斯梁的IRFS控制的GH移位是由非古典界面产生的。这些独特的现象为我们提供了一些指导，以测量IRF并扩展纳米级的界面光子学。
Classical electromagnetic boundary conditions (EMBCs) fail to describe quantum interface phenomena at nanoscale. Here, we construct the interface model with a transition layer describing the electromagnetic field inhomogeneity across the interface. Generalized nanoscale EMBCs are derived by introducing the magnetic interfacial response functions (IRFs) and are rewritten as three different forms based on Maxwell's equations in first order approximation. The corresponding Fresnel formula are further used to analyze the interfacial photonic phenomenon, demonstrating interesting behaviors of Brewster angle shifting, non-extinction at Brewster angle and distinctive non-classical absorption or gain effect at Brewster angle and the total internal reflection angles. IRFs-controlled GH-shifts of Gaussian beam near Brewster angle are generated by the non-classical interface. These unique phenomena give us some guidance to measure the IRFs and expand interface photonics in nanoscale.
