论文摘要
入射在表面上的放牧射击波几乎总是完全反射。在这里,我们专注于在放牧发生率时消除反射,采用量子力学的分解方法,并将其应用于控制单个电磁极化的Helmholtz方程。我们表明有两种方法,第一种方法是需要在放牧发生率下支持半结合状态的真正介电轮廓。第二个是允许表现出PT对称性的非热介质曲线,并在整个轮廓中支撑具有恒定强度的波。
Grazing incidence waves incident onto a surface will almost always be completely reflected. Here, we focus on removing reflection at grazing incidence, adopting the factorisation method from quantum mechanics and applying it to the Helmholtz equation that governs a single electromagnetic polarisation. We show that there are two approaches, the first is to require real dielectric profiles that support a half-bound state at grazing incidence. The second is to allow non-Hermitian dielectric profiles that exhibit PT symmetry, supporting waves with constant intensity throughout the profile.
