Quality factor measurements in cavities with mode overlap [PDF]
, 1994 A new method of measuring quality factors in cavities is presented. This method is well suited to measure quality factors in undamped cavities as well as in heavily damped cavities, and in addition this method provides a possibility of separating modes ...

Clamp-tapering increases the quality factor of stressed nanobeams
, 2019 Stressed nanomechanical resonators are known to have exceptionally high quality factors ($Q$) due to the dilution of intrinsic dissipation by stress. Typically, the amount of dissipation dilution and thus the resonator $Q$ is limited by the high mode ...

A Novel High Q Lamé-Mode Bulk Resonator with Low Bias Voltage
Micromachines, 2020 This work reports a novel silicon on insulator (SOI)-based high quality factor (Q factor) Lamé-mode bulk resonator which can be driven into vibration by a bias voltage as low as 3 V. A SOI-based fabrication process was developed to produce the resonators

Graphene-based tortional resonator from molecular dynamics simulation
, 2011 Molecular dynamics simulations are performed to study graphene-based torsional mechanical resonators. The quality factor is calculated by $Q_{F}=\omega\tau/2\pi$, where the frequency $\omega$ and life time $\tau$ are obtained from the correlation ...

Sodium-Based Cylindrical Plasmonic Waveguides in the Near-Infrared
Nanomaterials, 2022 Subwavelength optical field confinement and low-loss propagation are of great significance for compact photonic integration. However, the field confinement capability of plasmonic devices is always accompanied by the inherent Ohmic loss.

Very high quality factor measured in annealed fused silica
, 2004 We present the results of quality factor measurements for rod samples made of fused silica. To decrease the dissipation we annealed our samples. The highest quality factor that we observed was $Q=(2.03\pm0.01)\times10^8$ for a mode at 384 Hz. This is the
