▎ 摘　　要

NOVELTY - The attenuator has an equivalent surface plasmon waveguide (3) whose sides are respectively connected to one end of a microstrip signal conversion transition section (2) is symmetrically arranged. An other ends of the microstrip signal conversion transition section are respectively connected to the symmetrically arranged microstrip signal transmission section (1). A metal wire and a medium substrate hollowed-out portion are matched with each other and configured in an equal period arrangement and have a width of a waveguide are sequentially arranged in a medium layer of the equivalent surface plasmon waveguide from top to bottom. The metal wire is covered with a graphene sandwich structure (4). A dielectric substrate are made of Rogers RO4350B material. The material of the top metal conduction band layer (17) and the bottom full-cover metal layer (20) is copper. single layer of graphene is provided between the polyvinyl chloride layer and the separator paper. USE - Equivalent surface plasmon based dynamically adjustable graphene attenuator. ADVANTAGE - The dynamically adjustable graphene attenuator based on equivalent surface plasmon uses the electrolytic solution to regulate the conductivity of graphene, realizes the dynamic regulation of effective plasmon attenuation, and is easy to integrate on the plane. The attenuation is controlled by adjusting the applied voltage of graphene. The dynamically adjustable graphene attenuator has good application prospects in real-time dynamic control devices and circuits, and opens up new application prospects for equivalent plasma components.
