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.

我们应用了超材料的概念和功能在这些年来广泛探索，以将其用于高密度的气体流量血浆产生。通过超材料结构设计和实现了负渗透性空间，并在这些空间中注射了数百瓦的微波，导致具有负介电常数的高密度等离子体产生，这通过等离子体诊断证实。具有同时负介电常数和渗透性的状态导致动态生成负反射索引状态，而产生过程则在强大的非线性系统中。这项研究使我们能够提出新型的等离子来源，并验证非线性超材料的新技术用于工业活动。
