Identifying spurious modes in RF-MEMS resonators using photoelastic imaging

January 21, 2018
Author(s)
Vikrant J. Gokhale, Jason J. Gorman
This paper reports the first use of dynamic photoelastic imaging for identifying in-plane vibration modes in high-frequency MEMS resonators. In a set of width-extensional mode resonators (WE-BARs), we map fundamental width-extensional modes and unwanted

Parametric resonance in linear microresonators using analog feedback

January 21, 2018
Author(s)
Jason J. Gorman, Vikrant J. Gokhale
This paper reports on the design and implementation of an analog feedback controller for generating parametric resonance in linear microresonators that do not intrinsically demonstrate this phenomenon. It is shown that the controller produces a fundamental
