Experimental study of influence on electrostatic field measurement from air applied to electrostatic field sensor

Electrostatic Field Invisibility Cloak.

The invisibility cloak has been drawing much attention due to its new concept for manipulating many physical fields, from oscillating wave fields (electromagnetic, acoustic and elastic) to static magnetic fields, dc electric fields, and diffusive fields. Here, an electrostatic field invisibility cloak has been theoretically investigated and experimentally demonstrated to perfectly hide two dime...

The Electrostatic Field Is Conservative

Let's first consider the field of a point charge. dl The work done to move q from a to b:         b a b a l E l F d q d W Since E = E(r) (recall Coulomb's law), W is independent of the path.

Air-Solids Flow Measurement Using Electrostatic Techniques

Cepstrum Application to Electrostatic Field on Lightning Prediction

ABSTRACT: Electrostatic field measurements under storms have been widely measured in several aims, for current investigation, basically, corona and other phenoma [Lance et al. 1991]. On the other hand the application of the electrostatic field measurement results attractive for lightning hazard warning system. But several phenomena perturb and cause not a full representation of the storm electr...

An electrodynamic sensor for electrostatic charge measurement

Electrodynamic sensors are used in the process industry because they are low cost and robust. Though frequently used very little fundamental work on them has been reported. This paper describes an investigation into characteristics of hemispherically and rectangularly shaped sensors. Two parameters are investigated, the effect of sensor area on sensitivity and the spatial filtering effect of th...
