Electric Field Strength Due to Electric Excitation

2000
We start with the modified Maxwell equations without electric and magnetic charges, having constant scalars for the permeability µ and the permittivity ϵ. The following equations apply to a medium at rest: $$curlH = \in \frac{{\partial E}}{{\partial t}} + {{g}_{e}}$$ (1) $$- curlE = \mu \frac{{\partial H}}{{\partial t}} + {{g}_{m ...

Optical measurements of electric field strength in nonuniform fields

[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002
Describes optical measurements of the field-strength map in a liquid dielectric using the Kerr effect. Since electric lines of force are curved in a nonuniform field, the field strength can be measured on a plane which divides the center axis of two sphere electrodes into two equal parts and is perpendicular to the axis. On this plane, all of the field

Electric field strengths created by electrosurgical units

Proceedings of IEEE Symposium on Electromagnetic Compatibility, 2002
The electromagnetic environment found in hospital operating rooms can be quite hostile to electronic medical devices. The electromagnetic fields existing in the operating rooms are created by both distant sources such as AM and FM broadcast towers as well as local sources such as electrosurgical units.

Increasing electric field strength in polymer capacitors

Nanobiosystems: Processing, Characterization, and Applications X, 2017
Increased electric field breakdown in several polymer-based capacitor dielectrics, including biaxially oriented polypropylene, has been demonstrated using electron and hole blocking layers. Increased electric field breakdown translates into increased energy density.

Controlling flow direction in nanochannels by electric field strength

Physical Review E, 2015
Molecular dynamics simulations are conducted to study the flow behavior of CsF solutions in nanochannels under external electric fields E. It is found that the channel surface energy greatly affects the flow behavior. In channels of high surface energy, water molecules, on average, move in the same direction as that of the electric field regardless of ...

Reference Standard of Low-Frequency Electric Field Strength With Electrical Traceability

IEEE Transactions on Instrumentation and Measurement, 2023
For calibration of the environmental monitoring field meters, a reference standard of electric field strength based on parallel plates is established in the Primary electromagnetic laboratory FER-PEL in Croatia. The plate system incorporates guard ring electrodes with a set potential distribution to improve field uniformity within the center ...

Distribution fitting for long term electric field strength measurements

2017 40th International Conference on Telecommunications and Signal Processing (TSP), 2017
As a result of the enormous increase in usage of wireless systems; electromagnetic radiation (EMR) sources in residential areas as well as the exposed EMR levels has increased significantly. Therefore this study aims to determine the exposed E levels and characterize the electromagnetic environment on the basis of long term (24 hours) E measurements ...

Radiated electric field strength from high-power microwave systems

2006 17th International Zurich Symposium on Electromagnetic Compatibility, 2006
Intentional electromagnetic interference (IEMI) is an emerging threat and a new electromagnetic environment that has to be considered in the mitigation of electromagnetic compatibility problems. This paper presents an attempt to estimate the upper limitations of IEMI systems based on high-power microwave devices.

New Standard of Electric Field Strength

IEEE Transactions on Instrumentation and Measurement, 1970
A new technique is presented for establishing a standard of electric field strength using a highly conducting sphere. An analysis is made to determine the current on the sphere as a function of the electric field strength of an incident plane wave. A method of measuring that current using electronic circuitry and an optical indicator within the sphere ...

Electric Field Strength Dependent Electric Conductivity in Highly Insulating Materials

Materials Science Forum, 2006
The electric conductivity σ in highly insulating materials is determined by the equilibrium thermally generated carriers and by the injected carriers. The injected excess electrons will dominate the thermally generated electrons when the total number of injected electrons substantially exceeds the total number of initially empty electron traps existing
