Manipulation of Evanescent Wave Coupling in High-Q Terahertz All-Dielectric Metasurfaces
The resonance characteristics in periodically arranged artificial dielectric photonics and metasurfaces have attracted interests due to their growing applications in filters, low-threshold lasers, nonlinear generation of light, waveguides, chemical and biological sensors.Here, we experimentally demonstrate a family of silicon-based terahertz metasu
