dfdf The deflection decreases the distance between the membrane and the flat plate thereby increasing the Casimir force. So this system with positive feedback and has potential to be unstable [7]. If the strip is resistant enough, then the Casimir force can be countered by a restoring membrane forces called N. To be brief, I will just get to the results. For a dimensionless system characteristic contant, $K_c$, versus $\sigma_{\frac{L}{2}}$ called the normalized deflection, there are regions of stability and unstability. For smaller values of $\sigma_{\frac{L}{2}}$, we can get an equilibrium state for the membrane. The smallest value for stable equilibrium, $\sigma_{\frac{L}{2}}^{min}$, describes a state of minimum potential energy for the membrane strip, subject to Casimir force without any other external forces.
