Electron Heating by Non-Uniform Electric Field

1974
Current-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.

DEP-FFF: Field-Flow Fractionation Using Non-Uniform Electric Fields

Journal of Liquid Chromatography & Related Technologies, 1997
Dielectrophoresis (DEP) - the movement of particles in non-uniform electric fields - can be used in combination with Field Flow Fractionation (FFF) to separate particles with differing dielectric properties. An introduction is given to the technique of DEP-FFF and its application to the separation of cells and other particles.

Electric field simulation in a non-uniform field dielectric system

[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002
The 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.

Non-uniform FFTs in Near-field/Far-field Transformations

2012
Near-field antenna characterization consists of measuring, on proper scanning surfaces, the near-field radiated by an Antenna Under Test (AUT) and of determining, from those measurements, the far-field pattern (Near-Field/Far-Field – NFFF – transformation) [1]. Whenever possible, both the amplitude and the phase of the near-field are acquired on a sole

Vacuum polarization in some static non-uniform magnetic fields

Journal of Physics G: Nuclear and Particle Physics, 1996
Vacuum polarization in QED in the presence of some configurations of external magnetic fields is investigated. The configurations considered correspond to sourceless fields lying in a plane. The motion of a Dirac electron in these field configurations is studied and arguments are found to conclude that the lowest level gives the most important ...
