Key Points

  • The aim is to explore a switchable and tunable terahertz absorber utilizing a graphene and vanadium dioxide metamaterial.
  • Theoretical design based on transmission line theory and impedance matching.
  • Analysis of performance under varying polarization and incident angles.
  • Achieves stable terahertz absorption with adjustable properties based on the impedance.
  • Demonstrates effective performance across multiple polarization states and angles of incidence.

Abstract

A graphene–VO 2 -based asymmetric metamaterial absorber achieves switchable and tunable terahertz absorption, governed by impedance matching and transmission line theory, with stable performance under varying polarization and incident angles.
