Claim:
1. A metamaterial high-power microwave source, comprising: a cathode, a metamaterial slow-wave structure (SWS), a waveguide and coaxial line coupler which is located at one end of said metamaterial SWS, and a collector component which is located at the other end of said metamaterial SWS, wherein: said metamaterial SWS comprises a square waveguide and a metamaterial which is fixed at a central position of an inner cavity of said square waveguide; said waveguide and coaxial line coupler comprises a coupling waveguide and a coaxial line; said coupling waveguide comprises a rectangular coupling waveguide, a waveguide baffle which is located at one end of said rectangular coupling waveguide, and a waveguide connecting flange which is located at the other end of said rectangular coupling waveguide for fixedly connecting said rectangular coupling waveguide with said square waveguide; said coaxial line comprises a coaxial probe, two coaxial media, a medium fixing cylinder, and an output transferring cylinder; a central position of a lateral surface of said rectangular coupling waveguide has a circular hole thereon; one end of said medium fixing cylinder is embedded in an external side of said circular hole; the other end of said medium fixing cylinder is embedded in said output transferring cylinder; said medium fixing cylinder is filled with said two coaxial media; one end of said coaxial probe is fixedly connected with said metamaterial; and the other end of said coaxial probe passes through said two coaxial media; and said waveguide baffle has a pyramid-shaped square hole thereon for an electron beam to pass through; and said cathode is located at an external side of said square hole.
