Analytical and Spectro-Spatial Analyses of Nonlinear Metamaterials for Vibration Control, Energy Harvesting, and Acoustic Non-Reciprocity
This dissertation investigates the nonlinear wave propagation phenomena in nonlinear metamaterials with nonlinear chains and nonlinear resonators using analytical and spectro-spatial analyses. In the first part of the thesis, the nonlinear metamaterials are modeled as a chain of masses with …

Nonlinear Mechanical Metamaterial: A Novel Approach Towards Wideband Sound and Vibration Attenuation
Metamaterials have become very popular in the field of noise and vibration suppression, cloaking, wave guide, wave shield, wave absorber owing to its frequency dependent material properties. However, due to the dependency on the linear resonance, the performance of a linear metamaterial is …

Elastic wave tailoring at the macro/micro/nano- scales using intentional strongly nonlinear coupling
… approach, adopted in this work, is to build “metamaterials” using the existing materials as building blocks and leveraging local architecture to develop new engineered materials with extraordinary properties. The properties of metamaterials can be controlled by treating local architecture and …
