Experimental and Theoretical Characterization of Plasma Metamaterials

抄録

Plasma metamaterials, which have periodic microstructure partly composed of plasmas, show extraordinary responses against propagating electromagnetic waves. One of these responses arises from states with negative refractive index, and the corresponding plasma metamaterial is promising on microwave plasma generation as well as control of electromagnetic waves. Another good example is deformation of spoof surface plasmons using a microplasma array. These phenomena are characterized both experimentally and theoretically. Furthermore, both linear and nonlinear properties are explored, which are also distinguishable in comparison with the ordinary metamaterials.
