摘要

振动衰减在工程结构中起着至关重要的作用，其中超材料的应用日益广泛。这些结构重量轻，具有负质量特性，可以在特定频段减弱振动。第一部分研究了带有耦合声学黑洞和局部谐振器的超光束中的波传播，第二部分讨论了一维超材料链中的多稳定非线性振荡器。

Dynamics of Coupled Metamaterials: Acoustic Black Hole, Local Resonator & Multistable Oscillator

Vibration attenuation has played a crucial role in engineering structure, wherein metamaterials have found escalated usage. These structures can be cleverly built to be lightweight and have negative mass properties, which can attenuate waves at specific frequency bands. The first part studies wave propagation in meta-beam with coupled acoustic black holes and local resonators, whereas the second part discusses multi-stable nonlinear oscillators in a 1D metamaterial chain.
