可重构微波光子拓扑绝缘体
Reconfigurable Microwave Photonic Topological Insulator
摘要：
使用全三维有限元模拟和下划线的哈密顿模型，我们证明了可重构光子类似物的拓扑绝缘体上的可调杆在一个可重入的三维集总元件类型系统的规则晶格。可调谐性允许介质手性和其他性质的动态{ \it原位}变化，通过改变所有柱的相同参数，因此，在选择体/边缘配置方面具有很大的灵活性。此外，单向光子输运没有外部磁场证明。通过使用全有限元模拟以及简化的谐振子模型来说明这些想法。动态可重构性的建议系统铺平了道路，一类新的系统，可用于随机访问，拓扑信号处理和传感。
英文摘要：
Using full 3D finite element simulation and underlining Hamiltonian models, we demonstrate reconfigurable photonic analogues of topological insulators on a regular lattice of tunable posts in a re-entrant 3D lumped element type system. The tunability allows dynamical {\it in-situ} change of media chirality and other properties via alteration of the same parameter for all posts, and as a result, great flexibility in choice of bulk/edge configurations. Additionally, one way photon transport without an external magnetic field is demonstrated. The ideas are illustrated by using both full finite element simulation as well as simplified harmonic oscillator models. Dynamical reconfigurability of the proposed systems paves the way to a new class of systems that can be employed for random access, topological signal processing and sensing.
