Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] A microwave vortex wave generator based on artificial surface plasmons of the present invention adopts the traditional coplanar waveguide transmission line feeding mode, and utilizes annular artificial surface plasmon waveguides and circular metal patches to realize vortex waves radiation. The impedance design of the traditional coplanar waveguide transmission line is matched to 50 ohms, which is convenient for maximum power transmission; the transition of the microwave vortex wave generator based on the artificial surface plasmon from the traditional coplanar waveguide transmission line to the surface plasmon waveguide The unilateral corrugated stripline structure with gradually changing groove depth and the open metal ground structure are adopted to achieve wave number matching and impedance matching between the two waveguides, thereby maximizing power transmi...
