Emergence of the stochastic resonance in glow discharge plasma
نویسنده
چکیده
Stochastic resonance (SR) has been studied experimentally in a glow discharge plasma. For the SR phenomena, it is observed that a superimposed subthreshold periodic signal can be recovered via stochastic modulations of the discharge voltage. In the present experiments, induction of SR is quantified using the absolute mean difference (AMD). Comparison of the AMD techniques with respect to cross-correlation has also been shown.

Double Langmuir probe measurement of plasma parameters in a dc glow discharge
In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...
متن کاملNoise-invoked resonances near a homoclinic bifurcation in the glow discharge plasma.
Stochastic resonance (SR) and coherence resonance (CR) have been studied experimentally in discharge plasmas close to a homoclinic bifurcation. For the SR phenomenon, it is observed that a superimposed subthreshold periodic signal can be recovered via stochastic modulations of the discharge voltage. Furthermore, it is realized that even in the absence of a subthreshold deterministic signal, the...
متن کاملKinetic Model Study of Dry Reforming of Methane Using Cold Plasma
ABSTRACT In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated ...

In the agar/silver nanoparticle sample, as the irradiation time of argon glow discharge plasma ...
متن کاملDynamics of an excitable glow-discharge plasma under external forcing.
Glow discharge plasma in the excitable regime shows rich dynamical behavior under external forcing. By perturbing the plasma with a subthreshold sawtooth periodic signal, we obtained small subthreshold oscillations that showed resonance with the perturbation frequency. The resonance phenomenon can be useful to estimate characteristic of an excitable system. However, for suprathreshold perturbat...
