Electric field strengths created by electrosurgical units
Proceedings of IEEE Symposium on Electromagnetic Compatibility, 2002The 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, 2017Increased 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.

Direct measurement of the real strength of near-field electric field
Applied Physics LettersMeasurement of the real strength value of near-field electric fields is of great importance for understanding light–matter interactions in nanophotonics, which is a big challenge in the field. We developed in this study a theory and approaches for directly measuring the real strength of near-field electric fields by scattering type scanning near-field ...

Electric conduction of glasses at intermediate field strengths
Journal of Non-Crystalline Solids, 1996Abstract This study concerns four commercial glasses containing from 4 to 13 mol% alkali, a mixed alkali glass and three semi-conducting glasses containing from 5 to 10 mol% Fe2O3. Deviations from Ohm's law are detected somewhat beyond 104 V cm−1 and reach 10% at 105 V cm−1.

Electric Strength of Compressed Air in a Uniform Field
Nature, 1966IN a uniform field, Paschen's law, namely, breakdown voltage V = f(p.d) (where p is the gas pressure and d is the gap distance), holds for values of p up to about 10 atm., beyond which the improvement in electric strength of air becomes progressively less than would be expected from this relationship. Most published data extend only up to some 1,200 lb.

Electric Field Strengths at Totally Reflecting Interfaces
Journal of the Optical Society of America, 1965Incoming and reflected light waves superimpose to form a standing-wave pattern normal to a reflecting surface. For total internal reflection, a cosine distribution of the electric field amplitude in the denser medium joins onto the exponential distribution of the penetrating field in the rarer medium.

The electrical conduction of glass at high field strengths
Physica, 1956Synopsis The direct current ionic conductivity at very high field strengths of four kinds of glass has been measured. It appeared that above about 100 kV/cm the final conductivity increased exponentially with the field strength. The dependence on temperature could be described by the normal exponential Rasch and Hinrichsen law.

Field strength dependence of the electric birefringence of DNA
2007The field dependence of electric birefringence for calf thymus DNA nad λ DNA at various pH and various ionic strength was measured. The monodisperse and rigid polyions show linear dependence of electric birefringence on the electric field. In order to explain the experimental results the induced moment of a linear polyion is calculated based on the ...
