Fabrication and characterization of liquid metal-based micro-electromechanical DC-contact switch for RF applications

Cagatay E., Damgaci Y., Cetiner B.A., Biyikli N., Bilkent University - UNAM, TR

Electrowetting-on-dielectric (EWOD) is the phenomenon in which the wetting properties of a liquid are modified by the influence of an applied electric field. By EWOD, a conducting or non-conducting liquid can be moved using a [...]

Automatically Generated and Experimentally Validated System-Level Model of a Microelectromechanical RF Switch

Niessner M., Schrag G., Wachutka G., Iannacci J., Margesin B., Münich University of Technology, DE

In this work, we present a mixed-level model of an electrostatically actuated and viscously damped ohmic radio frequency (RF) microelectromechanical switch, which provides an accurate physical description of the device behavior and is suitable for [...]

A Study on Alleviating Deformation of MEMS Structure and Prediction of Residual Stress in Surface Micromachining

Kweon S., Hong S., Shin H., Jeon B., Samsung Advanced Institute of Technology, KR

When MEMS Structure, like RF switch, manufactured in high temperature is cooled down to the room temperature, the difference of the thermal expansion coefficients of structural materials, which are aluminum layer for electrical function and [...]

Computational Prototyping of an RF MEMS Switch using Chatoyant

Bails M., Martinez J.A., Levitan S.P., Avdeev I., Lovell M., Chiarulli D.M., University of Pittsburgh, US

In this paper we demonstrate the capabilities of our system-level CAD tool, Chatoyant, to model and simulate an RF MEMS switch. Chatoyant is a mixed signal, multi-domain CAD tool that can be used to design [...]
