Abstract: In the framework of wave-based method, we have examined swing motion control for double-pendulum and load-hoist models. Emphases are placed on wave scattering by the middle load mass in the double-pendulum model and on ...

Abstract: Due to the negative correlation between pressure resistance and waterborne sound insulation, lowimpedance soundproof materials can hardly work in deep water. Here, we propose a new mechanism to circumvent this problem by ...

Abstract: Space-coiling acoustic metamaterials dominated by the Fano resonance are being widely exploited for simultaneous control of sound isolation and air ventilation, and they usually achieve complete sound mitigation at multiple ...

Abstract: Interface states and edge states in periodic structures have been extensively investigated in the context of topological dynamics over the past decades. In this study, we propose an impedance method based on surface impedance ...
