HTS High Q Resonant Controller

High Tc superconductor (HTS) technology has been used to develop an advanced high Q resonant circuit and its devices. With a HTS, a very high Q circuit can be achieved; consequently special aspects such as high voltage generation and high current control can be theoretically and practically realized. Theoretical study has been carried out, as well as a practical approach has been made for the c...

Micro-Molded High Q Polymer Resonators for Optical Loss Determination

Replica molding of ultra-high-Q toroidal microresonators can produce polymer microresonators with material-limited quality factors (Q). This was demonstrated previously using polymers which cure thermally. In this work, high Q polymer microresonators were fabricated using the replica molding technique from previously uncharacterized polymers which require either a thermal or UV cure. The qualit...

High-Q MEMS Resonators for Laser Beam Scanning Displays

This paper reports on design, fabrication and characterization of high-Q MEMS resonators to be used in optical applications like laser displays and LIDAR range sensors. Stacked vertical comb drives for electrostatic actuation of single-axis scanners and biaxial MEMS mirrors were realized in a dual layer polysilicon SOI process. High Q-factors up to 145,000 have been achieved applying wafer leve...

Q measurement and simulation for RF coils

Introduction: A widely used figure of merit in radiofrequency (RF) coil construction and testing is the Q or ‘quality factor.’ Q is a measure of the spectral selectivity of the coil, Q = f0/Δf , where f0 and Δf are the central frequency and bandwidth (FWHM) of the resonance, respectively. A narrow bandwidth (high Q) excludes more noise and results in better signal to noise ratio. Q is also rela...
