Electroemulsification in a Uniform Electric Field

Langmuir, 2015
Emulsification using electric fields is an easy alternative to flow-induced drop breakup, and the former is reported to be more effective and economical than the latter, especially when the medium phase is poorly conducting and highly viscous. The emulsification of a coarse water-in-oil emulsion in a uniform electric field is studied.

A Probabilistic Interpretation of the IEC 61000-4-21 Threshold Levels for Field Uniformity in Ideal Reverberation Chambers

International Conference on Embedded and Multimedia Computing, 2020
Statistical field uniformity is the main property of reverberation chambers. In many key and seminal works, it is even the way reverberation chambers are defined.

Electron diffusion in a non-uniform electric field and a uniform magnetic field

Acta Physica Sinica (Overseas Edition), 1996
A Monte Carlo simulation technique has been used to model the electron transport behavior, especially the electron diffusion motion, in the cathode fall region of a glow discharge under the influence of a non-uniform electric field and a transverse magnetic field perpendicular to the cathode sheath electric field.

Improving Field Uniformity Using Source Stirring With Orbital Angular Momentum Modes in a Reverberation Chamber

IEEE Microwave and Wireless Components Letters, 2019
The orbital angular momentum (OAM) offers new degrees of freedom and finds application in communications and radar imaging. In this letter, the OAM is introduced for reverberation chamber (RC) measurements using OAM metasurfaces.
