Free‐space‐coupled wavelength‐scale disk resonators
Nanophotonics, 2022 Abstract Optical microresonators with low quality factor () can be efficiently excited by and scatter freely propagating optical waves, but those with high typically cannot. Here, we present a universal model for resonators interacting with freely propagating waves and show that the stored energy of a resonator excited by a plane ...

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

High-frequency nano-optomechanical disk resonators in liquids [PDF]
Nature Nanotechnology, 2015 Vibrating nano- and micromechanical resonators have been the subject of research aiming at ultrasensitive mass sensors for mass spectrometry, chemical analysis and biomedical diagnosis. Unfortunately, their merits diminish dramatically in liquids due to dissipative mechanisms like viscosity and acoustic losses.

Extraordinary acoustic transmission based on a both-sides-open disk resonator array
AIP Advances, 2019 Extraordinary acoustic transmission (EAT) is investigated numerically and experimentally using a square lattice array (SLA) of both-sides-open disk resonators (BSODRs) in a steel slab immersed in water. Each BSODR comprises a disk resonator sandwiched by

An Analtical Model for Vibration Analysis of Disk Resonator Gyroscopes
2022 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL), 2022 Disk resonator gyroscopes (DRGs) utilize the circular symmetry of a set of concentric rings to realize high-performance MEMS gyroscopes. We set forth an analytical method to calculate the mode shapes of the rings and then obtain the corresponding modal mass, Coriolis mass, and stiffness. Following the Ritz method, we minimize the total potential energy
