Parametric Drive: Resonators

This lecture covers the concept of parametric drive as an alternative actuation technique, where motion occurs above an instability threshold by tuning the natural frequency. It also delves into the equations and mathematical models related to parametric drive in resonators, discussing the implications of different parameters and their effects on the system's behavior. Additionally, the lecture explores the impact of surface effects and the surface-volume ratio on thin layers, emphasizing the importance of surface state as thickness decreases.
