Scalp Distribution of Electrical Fields Related to Blink Reflex

Journal of Clinical Neurophysiology, 1995
In 20 subjects the supraorbital nerve was stimulated and R1 recorded from electrodes placed over the ipsilateral orbicularis oculi muscle and from locations Fz, F8, F7, Cz, C6, C5, Pz, T4, and T3 on the scalp. The latter were referred either to an extracranial electrode or to Fz.

Optimization of optical parameters and electric field distribution in multilayers

Applied Optics, 1984
Multilayer coatings for high-power laser mirrors and lenses have been optimized by a particular constrained gradient method to reach together with a reduction of damage threshold (i.e., suppression of the peak electric field), good values of optical parameters (reflectance or transmittance).

Grouping the distributions of electric field amplitudes

2003 IEEE International Symposium on Electromagnetic Compatibility, 2003. EMC '03., 2003
A heuristic data-analysis method is introduced and applied to group electric field amplitude distributions into distinct groups according to their shape. The amplitudes are determined inside rectangular enclosures consisting of apertures, when the enclosures are illuminated by an external electric field.

On the distribution of electric fields in the magnetosphere

Journal of Geophysical Research, 1966
The magnetic storm theories of Alfven, Axford and Hines, and Dungey imply that an electrostatic potential difference exists across the magnetosphere. The detailed distribution of the resulting electric fields is, as yet, unknown. The present study is an attempt to solve this problem, assuming that a plasma with continuous energy spectrum is injected ...

Electric field distribution in an electroluminescent cell

Journal of Applied Spectroscopy, 1966
The theory of linear parameter distribution is discussed in relation to calculation of the intensity for an electroluminescent cell (EC). It is found that some of the formulas are applicable to the practical ranges of EC because the spatial region where nonlinear processes occur in strong fields is of restricted extent.

Electrical field distribution in transformer oil

IEEE Transactions on Electrical Insulation, 1992
Developments in Kerr electro-optic measurement technology at the laboratory have made possible high resolution electric field measurements in nonpolar liquids. The electric field distribution in transformer oil has been studied at service stress levels in both the transient and steady state.

Electric-field distribution in composite media

Physical Review B, 1998
Spatial fluctuations of the local electric field induced by a constant applied electric field in composite media are studied analytically and numerically. It is found that the density of states for the fields exhibit sharp peaks and abrupt changes in the slope at certain critical points which are analogous to van Hove singularities in the density of ...

Magnetic and electric fields of rotating charge distributions

American Journal of Physics, 1982
A charge distribution with axial symmetry is allowed to rotate with constant angular velocity around the axis of symmetry. The magnetic field of the resultant current density is calculated in terms of the electrostatic field of the charge distribution.

Electric field distribution in brain tumors

2014 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2014
About 37% of the brain tumors are malignant, causing brain cancers. Brain tumor stands as the second leading cause of cancer-related deaths in children and adults. Current standard of cure includes surgery, radiotherapy and chemotherapy. Brain surgery is too complex and involves more risks in treatment.

Electric field distribution in aluminum in strong magnetic fields

Soviet Journal of Low Temperature Physics, 1978
An anomalous electric field distribution was found in high purity aluminum under strong magnetic fields, produced by transverse displacement of current lines due to longitudinal inhomogeneity in H. The admissable inhomogeneity with use of the four-electrode method is determined by the effective magnetic field, with increase in which the requirement for
