Modeling of Dielectric Charging in RF MEMS

Category: Seminar

Professor Ashraf Alam, Purdue University. An insulator, by definition, carries no conduction current. Practical insulators (e.g. oxide) however seem to not know the definition and as voltages are ramped across them, charges injected from the electrodes accumulate within the oxide, and change …

Multiphysics and Multiscale Analysis of MEMS/NEMS

Category: Seminar

Professor Narayan R. Aluru, University of Illinois at Urbana-Champaign. Micro and nanoelectromechanical systems (MEMS and NEMS) are miniaturized sensors, actuators, devices and systems. Micromachined devices such as accelerometers, gyroscopes, pressure sensors, valves, pumps, single-chip …

Understanding and Improving Longevity In RF MEMS Capacitive Switches

Category: Seminar

Dr. Chuck Goldsmith, Ph.D., MEMtronics Corporation. Capacitive switching technology possesses many benefits over both conventional electronic switching devices and ohmic-contact MEMS switches at microwave and millimeter-wave frequencies. These benefits include a very high figure of merit, low …
