Numerical Capacitance Calculation for Mems Pressure Sensor by Method of Moments

Li P., Weber R.J., Iowa State University, US

MEMS-based capacitive pressure sensors have been widely used in many engineering applications. The design of a MEMS capacitance pressure sensor presents a number of challenges, one of which is the calculation of sensor capacitance and [...]

RF Measurement Techniques for Micro-Cantilever Characterization and Application

Wang C-H, Weber R.J., Iowa State University, US

The reflection coefficient (S11) of a one-port device is most sensitive to its input impedance if a matched condition is obtained. This implies two methods to measure the deflection-induced impedance change for a 1-port device [...]
