Modeling molecular response in uniform and non-uniform electric fields
The Journal of Chemical Physics, 2013The response of a molecule to an electric field E, often a model of environment, can be expressed in terms of a sum of power series expansions. We investigate the accuracy and limits of applicability of this expression using one-, two-, and three-dimensional models of the hydrogen-bonded complex, ClH:NH3.

Electric field simulation in a non-uniform field dielectric system
[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002The charge simulation method (CSM) is used to compute potential and electric field distribution in a 'hyperboloid-plane' electrode system. Electric field enhancement along the axis of the hyperboloid and within the dielectric is calculated at various interelectrode spacings and with various tip radii.

Electron Heating by Non-Uniform Electric Field
1974Current-voltage characteristics of asymmetrically necked samples cut from uniform single crystal of germanium become asymmetric at high electric fields. Current instabilities due to impact ionization are observed. A dc electromotive force arises in such samples in a large microwave field.

The Townsend coefficient in non-uniform electric fields
Journal of Physics D: Applied Physics, 1991A one-dimensional model of electron multiplication in a gas is considered by using a system of equations of moments. An approximate expression for the first Townsend ionization coefficient is derived. It is shown that for a linearly decreasing electric field, the multiplication cannot be characterized by a local transport coefficient, such as Townsend ...

The transport parameters of electrons in a non-uniform electric field
Plasma Sources Science and Technology, 2007The object of this work is to calculate the transport parameters of electrons in a non-uniform electric field. Knowledge of the transport parameters is necessary for any modeling in plasmas and the determination of certain properties in plasmas. The method used in our calculation is the Monte Carlo method; it takes account of several random phenomena ...

Flute instability in the presence of non-uniform electric fields
Plasma Physics, 1967A general equation describing the flute instability in a low-β plasma, in the presence of a non-uniform electric field perpendicular to the magnetic field, is derived from guiding centre equations. The equations obtained by Rosenbluth and Simon and by Damm et al. correspond to two different limiting cases of this more general equation.

Particle motion and drift in non-uniform electric fields
Physics of Plasmas, 2023This paper analyzes the two-dimensional motion of a charged particle in constant mutually perpendicular electric and magnetic fields. The magnetic field is assumed to be uniform, and the electric field components are assumed to be linear functions of the Cartesian coordinates.
