An electric field in the dielectric barrier electrode system is necessary for ozone production because produced by discharge of O2 under a high-intensity field. The gas plasmas contain energetic particles, such as electrons, ions, atoms, and radicals. recombination O atom plasma will form O3. In this paper, dependence DC formation on geometry gap between electrodes materials were examined using...
Excitons are neutral objects, that, naively, should have no response to a uniform, electric field. Could the Berry curvature of underlying electronic bands alter this conclusion? In work, we show that can indeed lead anomalous transport for excitons in 2D materials subject in-plane By considering constituent electron and hole dynamics, demonstrate there exists regime which corresponding velocit...
We considered the motion of DNA molecules through a hexagonal array under uniform electric fields as a Fokker-Planck process which is affected by the entropic barriers and we have simulated this motion by computer. We solved the Fokker-Planck equation with numerical simulation of the Brownian dynamics by the Euler method. For different DNA molecules, under different physical conditions, the mea...
Large-amplitude capillary waves on fluid sheets are computed in the presence of a uniform electric field acting in a direction parallel to the undisturbed configuration. The fluid is taken to be inviscid, incompressible and non-conducting. Travelling waves of arbitrary amplitudes and wavelengths are calculated and the effect of the electric field is studied. The solutions found generalize the e...
By molecular dynamics simulations we investigate the transport of charged polymers in confinement, under externally applied electric fields, in straight cylinders of uniform diameter and in the presence of monovalent or multivalent counterions. The applied electric field has two components; a longitudinal component along the axis of the cylinder and a transversal component perpendicular to the ...
Laser–atom interaction can be an efficient mechanism for the production of coherent electrons. We analyze the dynamics of monoenergetic electrons in the presence of uniform, perpendicular magnetic and electric fields. The Green function technique is used to derive analytic results for the field– induced quantum mechanical drift motion of i) single electrons and ii) a dilute Fermi gas of electro...
In most of microwave heating applications obtaining uniform heating patterns in certain regions of the applicator is a key issue. In this paper, the proposed solution for achieving electric field uniformity consists of designing the configuration of the feeding system in a multimode cavity by means of Genetic Algorithms. The feeding system is constituted by waveguides or slots arrays. The elect...
