The invention discloses an artificial surface plasma coupled resonant cavity waveguide. The waveguide is formed by arranging artificial surface plasma resonant cavities, which are copper sheet grids printed on a dielectric bottom plate or metal helix structures supporting a magnetic dipole mode. The waveguide realizes transmission of surface electromagnetic wave via weak coupling among the surface plasma resonant cavities. The surface plasma resonant cavities support a four-order resonant mode and an eight-order resonant mode having quadruple rotating symmetry, so the surface electromagnetic wave is not reflected or scattered when passing through the bent waveguide composed of the resonant cavities and having not bent radius, then perfect transmission of surface electromagnetic wave is realized, and a new integrated platform is provided for future high integrated plasma circuits.
