Design Parameters for “Robust” Superoleophobicity Surfaces

Law K-Y, Zhao H., Park K.C., Xerox Corporation, US

Earlier we reported the fabrication of a model superoleophobic surface comprising ~3-micron diameter pillar arrays on Silicon. Results showed that both surface fluorination and the re-entrant geometry are crucial in achieving the superoleophobicity with hexadecane [...]

High-fidelity MEMS Switch Model

Park K.C., Park Y.H., Miyazaki Y., Park K.C., Park Y.H., University of Colorado at Boulder, US

MEMS switches have used in a wide variety of microwave applications because of low loss and small measurable signal distortion since the switching action is accomplished by mechanical contact. While various microswitches are currently being [...]

Coupled Substrate-resonator-electrostatic Simulation and Validation fo High-Q MEMS Resonator Performance

Park K.C., Park Y.H., Park K.C., Park Y.H., University of Colorado at Boulder, US

Vibration energy transmission from MEMS resonator through anchor to substrate, viz., anchor loss, is examined by utilizing the coupled substrate-resonator-electrostatic numerical model. The resonator is electrostatically excited beam-type structure anchored at both ends onto multi-layered [...]
