论文摘要
反射和传播的左/右不对称非常弱，由一层拓扑绝缘子在各向异性介电材料的顶部提供，但是通过使用两种类型材料的定期多层材料，可以非常明显地增强它。这是实现单向Terahertz设备的有吸引力的前景，因为两种类型的材料都可以使用标准的物理蒸气沉积技术生长。
Very weak left/right asymmetry in reflection and transmission is offered by a layer of a topological insulator on top of a layer of an anisotropic dielectric material, but it can be enhanced very significantly by using a periodic multilayer of both types of materials. This is an attractive prospect for realizing one-way terahertz devices, because both types of materials can be grown using standard physical-vapor-deposition techniques.
