Dual‐Band Valley Hall Topological Photonic Crystal in the Terahertz Regime and Its Directional Radiation

ABSTRACT Valley‐Hall photonic crystals offer promising opportunities for topological wave routing, frequency‐selective manipulation, and directional radiation, yet most experimentally demonstrated terahertz (THz) systems operate within a single topological bandgap. Here, we propo...
