摘要

摘要阐述了光在各向同性电介质和光学各向异性材料（液晶或超材料）之间的边界处的折射，特别是对各向异性材料双折射光轴和材料表面之间角度的依赖性。显示了由液晶光学响应或潜在的正负各向异性超材料引起的负折射和正折射的不同状态，确定了不同的折射和反射状态。理论分析通过时域有限差分模拟进行了验证，并在选定的相关文献中进行了介绍。更广泛地说，这项工作有助于开发和理解各向异性液晶型软超材料，以实现基于光学各向异性的新型光子现象。

Refraction of light on flat boundary of liquid crystals or anisotropic metamaterials

ABSTRACT Refraction of light at a boundary between an isotropic dielectric and an optically anisotropic material – liquid crystalline or metamaterial – is elaborated, especially the dependence on the angle between the anisotropic material birefringence optical axis and the material surface. Different regimes of negative and positive refraction are shown, caused by the liquid-crystalline optical response or potential negative-positive anisotropic metamaterial, identifying distinct regimes of refraction and reflection. The theoretical analysis is verified with finite-difference time-domain simulations and presented in the context of selected related literature. More broadly, this work is a contribution towards developing and understanding anisotropic liquid crystal-type soft metamaterials to achieve novel photonic phenomena based on optical anisotropy.
