Topological Robust Corner States of a Two-Dimensional Square Lattice with Symmetry in Fully Coupled Dipolar Arrays
Chen Luo, Xiang Zhou, Hui-Chang Li +3
Higher-order topological insulators(HOTIs) is an exciting topic. We constructed a square lattice dipole arrays, it supports out-of-plane and in-plane modes by going beyond conventi…
Realization of a photonic topological insulator in Kagome crystals at terahertz wavelengths
Yun Shen, Jie Ji, Le Zhang +8
Topological systems are inherently robust to disorder and continuous perturbations, resulting in dissipation-free edge transport of electrons in quantum solids, or reflectionless g…
Broadband energy squeezing and tunneling based on unidirectional modes
Lujun Hong, Yazhou Wang, Yun Shen +4
Energy squeezing attracts many attentions for its potential applications in electromagnetic (EM) energy harvesting and optical communication. However, due to the Fabry-Perot resona…
Slow wave and truly rainbow trapping in one-way terahertz waveguide
Jie Xu, Panpan He, Delong Feng +4
Slow or even stop electromagnetic (EM) waves attract researchers' attentions for its potential applications in energy storage, optical buffer and nonlinearity enhancement. However,…
