Abstract
微小サイズのプラズマ(マイクロプラズマ)をプラズマ周波数が20-30GHzとなるように生成し、1次元ないし2次元の周期構造を作製した。ここで、プラズマ周波数以下の領域となるマイクロ波帯ではマイクロプラズマは金属等価に振舞う。この領域で観測されるマイクロ波の伝搬について、禁制帯および局在表面プラズモン様モードに着目してその検出を行うと同時に、理論的に分散関係の導出を行い、実験結果との比較検討を行った。
A microplasma, which has smaller size than a conventional plasma and has plasma frequency at 20-30 GHz, was generated and its integration formed one-dimensional and two-dimensional periodic structures. We observed microwave propagation through these structures below the plasma frequency, where the microplasmas show metal-like properties. Observed band gaps and localized-surface-plasmon-like modes were compared with theoretical predictions.
