Spatial Modulation of Nonlinear Flexural Vibrations of Membrane Resonators
Spatial Modulation of Nonlinear Flexural Vibrations of Membrane Resonators
We study the vibrational motion of mechanical resonators under strong drive in the strongly nonlinear regime. By imaging the vibrational state of rectangular silicon nitride membrane resonators and by analyzing the frequency response using optical interferometry, we show that, upon increasing the driving strength, the membrane adopts a peculiar deflection …
