| Research Abstract |
We applied metamaterials, whose concepts and functions have been extensively explored for these years, to high-density gas-discharge plasma generation. Negative-permeability spaces were designed and achieved by metamaterial structures, and injection of microwaves at several hundreds of watts into these spaces led to generation of high-density plasmas with negative permittivity, which was confirmed by plasma diagnostics. States with simultaneous negative permittivity and permeability led to dynamic generation of negative-refractive-index states, and generation processes were in strong nonlinear systems. This study allows us to propose novel plasma sources and to verify new techniques of nonlinear metamaterials for industrial activities.
