Optimal Design of a Polyaniline-Coated Surface Acoustic Wave Based Humidity Sensor

open access: yesSensors, 2013
This paper presents an optimal design for a new humidity sensor composed of a dual-resonator oscillator configuration with an operation frequency of 300 MHz, and a polyaniline (PANI) coating deposited along the resonation cavity of the sensing device. To

Resonances and resonance widths [PDF]

open access: yes, 1986
Two-dimensional betatron resonances are much more important than their simple one-dimensional counterparts and exhibit a strong dependence on the betatron phase advance per cell. A practical definition of ''width'' is expanded upon in order to display these relations in tables.

Resonating bipolarons [PDF]

open access: yesEurophysics Letters (EPL), 2006
Electrons coupled to local lattice deformations end up in selftrapped localized molecular states involving their binding into bipolarons when the coupling is stronger than a certain critical value. Below that value they exist as essentially itinerant electrons.

Experimental and Numerical Investigation of Termination Impedance Effects in Wireless Power Transfer via Metamaterial

open access: yesEnergies, 2015
This paper presents an investigation of the transmitted power in a wireless power transfer system that employs a metamaterial. Metamaterials are a good means to transfer power wirelessly, as they are composed of multiple inductively-coupled resonators ...

Resonant Nucleation [PDF]

open access: yesPhysical Review Letters, 2005
We investigate the role played by fast quenching on the decay of metastable (or false vacuum) states. Instead of the exponentially-slow decay rate per unit volume, $ _{\rm HN} \sim \exp[-E_b/k_BT]$ ($E_b$ is the free energy of the critical bubble), predicted by Homogeneous Nucleation theory, we show that under fast enough quenching the decay rate is a

Nucleon resonances in the fourth-resonance region [PDF]

open access: yesThe European Physical Journal A, 2011
Nucleon and $ $ resonances in the fourth resonance region are studied in a multichannel partial-wave analysis which includes nearly all available data on pion- and photo-induced reactions off protons. In the high-mass range, above 1850\,MeV, several alternative solutions yield a good description of the data.

Resonators with tailored optical path by cascaded-mode conversions [PDF]

open access: yes, 2022
Optical resonators enable the generation, manipulation, and storage of electromagnetic waves. They are widely used in technology and fundamental research, in telecommunications, lasers and nonlinear optics, ultra-sensitive measurements in cavity optomechanics, and the study of light-matter interactions in the context of cavity QED.

An example of design, optimization, stabilization and noise performances of resonator-based optoelectronic oscillators

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2019
In this paper we talk about oscillators of optoelectronic type with intensity modulators and high-quality optical resonators technology. This subject is illustrated by an example of realization from the material to the characterization of the realized ...

Simulation of High-Power Klystrons with Heterogeneous Focusing Magnetic Field

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2022
The work shows a significant effect of the focusing magnetic field on the output characteristics of the klystron. When the calculations are done using nonlinear one-dimensional models, optimization of the parameters makes it possible to obtain versions ...

Resonances in a box [PDF]

open access: yesJournal 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.
