A Tunable MEMS Capacitor

Model ID: 123


In an electrostatically tunable parallel plate capacitor, the distance between the two plates can be modified by a spring, as the applied voltage changes.

For a given voltage difference between the plates, the distance of the two plates can be computed, if the characteristics of the spring are known. Knowledge of this means that the distance between the plates can be tuned via the spring.

In this model, the electrostatic field is simulated out for a given distance.
