Extensive development of micro/nano-electromechanical systems (MEMS/NEMS) has
resulted in technologies that exhibit excellent performance over a wide range of applications …

Phononic crystals/metamaterials are attracting increasing interest because of their large
variety of applications at both the macro and micro scales. In this work, a new metamaterial …

Adaptive oscillators are a type of nonlinear oscillator that are capable of learning and storing
information in plastic states. Here, a typical mechanical pendulum is modified to have an …

Synchronization, as a unique phenomenon, has been extensively studied in biology, chaotic
systems, nonlinear dynamics, quantum information, and other fields. Benefiting from the …

We demonstrate synchronization between two intrinsically coupled oscillators that are
created from two distinct vibration modes of a single micromachined disk resonator. The …

In contrast to the well-known phenomenon of frequency stabilization in a synchronized noisy
nonlinear oscillator, little is known about its amplitude stability. In this paper, we investigate …

Mechanical resonators that possess coupled modes with harmonic frequency relations have
recently sparked interest due to their suitability for controllable energy transfer and non …

As a subset of nonlinear oscillators, adaptive oscillators are often constructed by appending
additional dynamic states to a nonlinear oscillator. Adaptive oscillators have dynamic states …

In this letter, we investigate the dynamics of injection-locking a nonlinear micromechanical
oscillator operating in different regimes of electromechanical nonlinearity to an external tone …

This paper reports experimental results demonstrating significant gains in frequency stability
for bulk acoustic wave (BAW) silicon disk resonator oscillators due to the locking of …
