چکیده
We present a numerical investigation of an acoustic sensor based on cylindrical resonator to monitor the properties liquids flowing in tube. The design consists hollow washer surrounding tube, which carries liquid, and can be filled during sensing process. Due impedance mismatch between liquid solid washer, we demonstrate presence high-quality factor resonances associated with (such as velocity, density, or viscosity) appearing sharp spectral features transmission detection measurements. An appropriate choice geometrical parameters allows either obtain two distinct overlap narrow resonance broad achieve Fano-type from their interaction. sensitivity are investigated function parameters. show that for highly viscous fluids, vanishing very peaks avoided by increasing thickness and, therefore, decreasing quality factors. calculations performed framework finite element method. Our provides promising platform several characteristics tubes.

متن کاملDielectrically-Loaded Cylindrical Resonator-Based Wireless Passive High-Temperature Sensor
The temperature sensor presented in this paper is based on a microwave dielectric resonator, which uses alumina ceramic as a substrate to survive in harsh environments. The resonant frequency of the resonator is determined by the relative permittivity of the alumina ceramic, which monotonically changes with temperature. A rectangular aperture etched on the surface of the resonator works as both...

Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
