| Outline of Final Research Achievements |
We controled GHz elastic waves propagating on plates with nanoscale thickness using artificial phononic structures as follows. We designed double negative flexural wave metamaterials and simulated negative refractions. We designed a plasmonic phononic crsytal with perfect phononic bandgap. We imaged surface acoustic waves on a microsphere-based elastic metamaterial structure. We measured reflectivity change on split ring resonators due to mechanical vibrations.

| Academic Significance and Societal Importance of the Research Achievements |
従来の弾性メタマテリアルの周波数帯よりも高いGHz周波数領域で動作するフォノニックメタマテリアルが実現できることを、シミュレーションや試料作製、光学測定実験によって我々は示した。本研究は、フォノニックメタマテリアルの新しい科学を切り開き、将来的にはMEMS（マイクロマシン）技術との融合させることによって、新しいマイクロスケールの振動制御などの研究につながるものである。
