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.
