▎ 摘　　要

NOVELTY - The waveguide has two silicon oxide substrates provided with step-shaped strip-shaped bulges on a silicon substrate. Each step-shaped strip-shaped bulge is matched with a step-shaped strip-shaped groove. A step-shaped strip-shaped projection is formed with the step-shaped strip-shaped groove. The silicon oxide substrates are provided with graphite alkene layers. USE - Graphene surface plasma polarized wave variable propagation width waveguide. ADVANTAGE - The waveguide is convenient to process and easy to integrate, has light weight and better application prospect, and realizes working ability at frequency points.
