Tuning of a MEMS RF Filter

Hammad B.K., Abdel-Rahman E.M., Nayfeh A.H., Virginia Polytechnic Institute and State University, US

We present an analytical model and use it to find closed-form expressions describing the response of a tunable MEMS RF filter. The filter is made of two identical clamped-clamped micro-beams suspended over input and output [...]

Dynamic Simulations of a Novel RF MEMS Switch

Younis M.I., Abdel-Rahman E.M., Nayfeh A.H., Virginia Tech, US

We present a dynamic analysis of a novel RF MEMS switch utilizing the dynamic pull-in phenomenon. We study this phenomenon and present guidelines about its mechanism. We propose to utilize this phenomenon to design a [...]

Superharmonic Resonance of an Electrically Actuated Resonant Microsensor

Abdel-Rahman E.M., Nayfeh A.H., Virginia Polytechnic Institute and State University, US

We investigate the response of a microbeam-based resonant sensor to a superharmonic electric actuation. The model incorporates the nonlinearities associated with moderately large displacements and electric forces. The method of multiple scales is used to [...]
