▎ 摘　　要

NOVELTY - A graphene planar plasma artificial structure based phase shifter has a silicon dioxide/silicon substrate, a graphene film arranged on the substrate, and open grooves periodically formed in the graphene film. USE - Graphene planar plasma artificial structure based phase shifter. ADVANTAGE - The shifter has compact structure, and can realize easy planar integration and work in a terahertz low-frequency stage. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene planar plasma artificial structure based phase shifter.
