A Resonant Pressure Microsensor with a Wide Pressure Measurement Range

open access: yesMicromachines, 2021
This paper presents a resonant pressure microsensor with a wide range of pressure measurements. The developed microsensor is mainly composed of a silicon-on-insulator (SOI) wafer to form pressure-sensing elements, and a silicon-on-glass (SOG) cap to form

High Quality Factor, High Sensitivity Metamaterial Graphene—Perfect Absorber Based on Critical Coupling Theory and Impedance Matching

open access: yesNanomaterials, 2020
By means of critical coupling and impedance matching theory, we have numerically simulated the perfect absorption of monolayer graphene. Through the critical coupling effect and impedance matching, we studied a perfect single-band absorption of the ...

On the calculation of the quality factor in contemporary photonic resonant structures. [PDF]

open access: yesOptics Express, 2019
The correct numerical calculation of the resonance characteristics and, principally, the quality factor Q of contemporary photonic and plasmonic resonant systems is of utmost importance, since Q defines the bandwidth and affects nonlinear and spontaneous

Dynamic focusing with high-quality-factor metalenses.

open access: yesNano letters (Print), 2020
Metasurface lenses provide an ultrathin platform in which to focus light, but weak light-matter interactions limit their dynamic tunability. Here we design sub-micron-thick, ultrahigh quality factor (high-Q) metalenses that enable dynamic modulation of ...
