| Outline of Final Research Achievements |
By combining the wave filtering method that measures amplitudes of the wave propagating for a specific direction and the wave control method that reduces the specific wave propagation, the wave valve was established that allows the wave propagation for only one direction. Furthermore, the energy trapping control was presented that confines disturbance energy within the designated region by using two wave valves arranged to face each other. Based on this method, it is possible to generate a vibration-free state in a vibration-unacceptable region and to avoid the new resonances in a wide region of the target structure.

| Academic Significance and Societal Importance of the Research Achievements |
従来の波動制御法においては，構造物中に無振動状態を生成したとしても，非制御領域において新たな共振現象が発生してしまい，安定性に問題があった．そこで，構造物中の限られた領域に外乱エネルギを封じ込めることにより問題を解決した．能動振動・音響制御分野において，エネルギの封じ込めという概念に依拠した手法はほとんど存在せず，学術的な意義は大きいと考える．
