Parametric Resonance in Electrostatically Actuated Micromirrors [PDF]

IEEE Transactions on Industrial Electronics, 2017
We consider an electrostatically actuated torsional micromirror, a key element of recent optical microdevices. The mechanical response is analyzed with specific emphasis on its nonlinear features. We show that the mirror motion is an example of parametric resonance, activated when the drive frequency is twice the natural frequency of the system.
