    Design optimization of a microelectromechanical electric field sensor using genetic algorithms 

    Roy, Mark (2012-09-24)
    This thesis studies the application of a multi-objective niched Pareto genetic algorithm on the design optimization of an electric field mill sensor. The original sensor requires resonant operation. The objective of the ...

    Electrostatic testing of simple MEMS structures 

    Cheng, Kar Mun (2006-07-12)
    In this thesis, an adapted form of dynamic Electrostatic Force Microscopy is presented as an alternative technique for non-contact dynamic characterization of beam resonators. The actuation of the test resonant beam was ...

    MEMS micro-ribbons for integrated ground plane microstrip delay line phase shifter 

    Yip, Joe (2008-01-18)
    A delay line phase shifter for the 30-70 GHz range is presented that uses an aluminum micro-ribbon array fabricated in the ground plane of a microstrip transmission line. Phase shift is achieved by changing the propagation ...
