Experimental and Theoretical Study of Internal Resonance in Micro-Mechanical Resonators

Name: Jun Yu

Abstract:
Extensive development of Micro-Electro-Mechanical-Systems/Nano-Electro-Mechanical-Systems (MEMS/NEMS) has resulted in technologies that exhibit superb performance over a wide range of applications. Many of these applications benefit from resonance phenomena by employing micro/nanoscale mechanical resonators. In the past decade, there has been a growing interest in using more than one vibrational mode for the enhanced functionality of MEMS/NEMS. In this category of understanding and exploiting multi-mode nonlinear characteristics in MEMS/NEMS, internal resonance (IR) attracts much attention from researchers. The thorough study on IR provided in this dissertation paves the way to constructively implement IR features in resonator-based applications to improve performance. At the same time, deeper insight into the nonlinear dynamics of IR can be utilized in fundamental research.
