Electric field effects in RUS measurements

Ultrasonics, 2010
Much of the power of the Resonant Ultrasound Spectroscopy (RUS) technique is the ability to make mechanical resonance measurements while the environment of the sample is changed. Temperature and magnetic field are important examples. Due to the common use of piezoelectric transducers near the sample, applied electric fields introduce complications, but

Phase measurement for electric field tomography

Physiological Measurement, 2008
The basic principles of electric field tomography (EFT) are briefly explained. EFT system numerical simulation results are given. The comparison of images reconstructed by systems with planar and round electrode arrays is presented. Some aspects of transmitting and measuring stages are discussed.

Electric Vehicle Magnetic Field Measurement

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">The magnetic field generated by electric vehicles are the subject of public concern. Preliminary spot measurement results confirm that electric vehicles generate transient magnetic fields which may be quantified with appropriate instrumentation.

The Measure of Atmospheric Electric Field

2011
We have developed a prototype of a sensor able to detect and measure electric fields in the atmosphere. The atmosphere is a gaseous envelope gravitationally bound to the Planet. Different atmospheres have very different properties. For instance, the atmosphere of Venus is very thick and cloudy, and is responsible for producing the very high surface ...

Electric field measurements above thunderstorms

Journal of Atmospheric and Terrestrial Physics, 1957
Abstract The electric field and conductivity of the atmosphere were measured above thunderstorms in the central Florida area in a series of twenty-five balloon flights made at altitudes ranging from 70,000 to 90,000 ft above sea level. These tests indicate that at these altitudes and for the storms investigated there is a positive current of ...
