A quadrupolar-symmetric VO2 metasurface with edge-plasmonic dipoles for ultrabroadband and polarization-insensitive terahertz absorption.

Obtaining broadband terahertz (THz) absorbers with simple structures is crucial for terahertz device research. In light of the temperature-controlled phase transition property of vanadium dioxide (VO2), this study designed and realized a dynamically…
