Inclination Sensor With a Wide Angle Measurement Range Using Half-Wavelength Microstrip Resonator
IEEE Access, 2023 In this article, a new inclinometer concept based on an angular half-wavelength microstrip resonator is presented. The inclinometer has a wide dynamic range of 84° (B142°) which can be extended to 180° through a simple modification ...

A Closed Cavity Ultrasonic Resonator Formed by Graphene/PMMA Membrane for Acoustic Application
Micromachines, 2023 A graphene/poly(methyl methacrylate) (PMMA) closed cavity resonator with a resonant frequency at around 160 kHz has been fabricated. A six-layer graphene structure with a 450 nm PMMA laminated layer has been dry-transferred onto the closed cavity with an

Cylindrical Resonator Sectorally Filled With DNG Metamaterial and Excited by a Line Source [PDF]
, 2012 A circular cylindrical resonator with metallic walls is analyzed in the phasor domain. The resonator contains a wedge of double-negative (DNG) metamaterial that is anti-isorefractive to the double-positive (DPS) material filling the remaining volume of ...

Journal of Mathematical Physics, 2000 We investigate a numerical method for studying resonances in quantum mechanics. We prove rigorously that this method yields accurate approximations to resonance energies and widths for shape resonances in the semiclassical limit.

High-sensitivity optical monitoring of a micro-mechanical resonator with a quantum-limited optomechanical sensor [PDF]
, 2006 We experimentally demonstrate the high-sensitivity optical monitoring of a micro-mechanical resonator and its cooling by active control. Coating a low-loss mirror upon the resonator, we have built an optomechanical sensor based on a very high-finesse ...

Overstability and resonance [PDF]
Annales de l'Institut Fourier, 2003 We consider a singularity perturbed nonlinear differential equation εu ′ =f(x)u++εP(x,u,ε) which we suppose real analytic for x near some interval [a,b] and small |u|, |ε|. We furthermore suppose that 0 is a turning point, namely that xf(x) is positive if x≠0.

The Resonator Banjo Resonator, part 2: What makes them really crack? [PDF]
, 2015 A simple experiment quantifies the difference between the sound production of a banjo with and without a resonator back. Driven by a small tweeter mounted inside the pot, for frequencies above about 4500 Hz, the produced external sound is 6 to 10 dB ...

Performance Analysis of Resonant-Fin Transistors and Their Application in RF-Circuit Design
IEEE Access, 2022 Emerging new communication standards like 5G or 6G aggravate the circuit design of radio-frequency generation systems as they constantly increase demand on high bandwidths, low latency, and high spectral purity.
