Terahertz Plasmonic Transport in Topological Valley Metal-slabs
Xiang Zhou, Hui-Chang Li, Yun Shen
Topological photonic devices have attracted great attentions in terahertz (THz) and optical regimes due to their robust protected transport properties. However, it remains challeng…

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…
