Electromagnetic waves at grazing incidence onto a planar medium are analogous to zero energy quantum particles incident onto a potential well. In this limit waves are typically completely reflected. Here we explore dielectric profiles supporting optical analogues of ‘half–bound states’, allowing for zero reflection at grazing incidence. To obtain these profiles we use two different theoretical approaches: supersymmetric quantum mechanics, and direct inversion of the Helmholtz equation, showing that discretized approximations to these profiles exhibit low reflectivity close to grazing incidence.

超对称、半束缚态和掠入射反射

掠入射到平面介质上的电磁波类似于入射到势阱上的零能量量子粒子。在此极限波通常被完全反射。在这里,我们探索了支持“半束缚态”光学类似物的介电分布,允许在掠入射时实现零反射。为了获得这些剖面,我们使用了两种不同的理论方法:超对称量子力学和亥姆霍兹方程的直接反演,表明这些剖面的离散近似表现出接近掠入射的低反射率。
