In this paper, a novel resonant magnetometer is demonstrated based on MEMS Technology. The proposed sensor consists of a square extensional mode resonator with a planar induction coil placed on top of the resonant plate. The sensor employs capacitive driving and electromagnetic induction to detect external magnetic field through the electromotive force in the induction coil. The operation principle,...
An Efficient modeling technique based on immune algorithm and BP neural network is presented for the design of RF MEMS phase shifter. Three sensitive parameters are selected according to complicated three-dimensional structure design of an RF MEMS phase shifter and used as inputs of neural network. In the model, immune algorithm is first used for global search and then BP algorithm for local search...

The operating principle of the RF MEMS phase shifter is described. Two improved design approaches based on the CPW discontinuities to decrease the return loss are proposed. By using network theory and CST microwave studio simulation tool, the proposed RF MEMS phase shifters are modeled. Simulation results for the two designs are compared and discussed based on the analysis. Simulation results show...
