Parametric Simulation of MEMS Based on Automatic Differentiation of Finite Element Codes

Kolchuzhin V.A., Mehner J.E., Gessner T., Doetzel W., Chemnitz University of Technology, DE

The key idea of the presented approach, which account for parameter variations in a single finite element run, is to compute not only the governing system matrices of the FE problem but also their partial [...]

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 [...]

Scalable Macromodels for Microelectromechanical Systems

Srinivasan V., Jog A., Fair R.B., Duke University, US

A fully automatic macromodeling methodology to generate scalable reduced-order models for microelectromechanical systems is presented in this paper. Krylov subspace methods are used to generate reduced-order models from detailed higher-order models of the device under [...]
