IN NATURE of Oct. 25 is a communication from Mr. J. Mazur, under the heading of: “Change of the Dielectric Constant of Ethyl Ether with Temperature”. This appears a suitable opportunity for raising a question to which I have previously alluded in sever

The term dielectric constant refers to a material’s ability to concentrate anelectric field.—IEEE Spectrum, 15...
1.The electric-field intensity inside and outside of the spherical cavity in polarized homogeneous dielectric are recalculated by use of Laplace equation, and the conclusion are different from those in some textbooks.运用拉普拉斯方程对均匀极化电介质被挖出一个球形空腔的内、外电场强度进行了新的运算,得...
Electrostatics:This is the sub-field of electromagnetics describing an electric field due to static (non-moving) charges. As an approximation of Maxwell’s equations, electrostatics can only be used to describe insulating, or dielectric, materials entirely characterized by electric permittivity. When ...
The modeling results show that E-field enhancements as large as a factor of 4 can be present at the defects. The enhancement shows a complex dependence on the size, depth and dielectric constant of the seed material. In general, defects initiated ,by large, shallow seeds produce the largest...
The maximum output of high-power pulsed lasers is always determined by laser resistance of gratings and this resistance is strongly dependent on the local near electric field intensity in the grating structure. We presented a novel method of reducing electric-field-enhancement in metal-dielectric ...
electrostatic field- electric field associated with static electric charges field of force,force field,field- the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it ...
Decreasing the electric pulse duration into the nano- second range engages different mechanisms of membrane potential build-up (dielectric stacking instead of Maxwell-Wagner polarization) and enables direct effects of the electric field on intracellular mem- branous structures4,10–12, thereby giving ...
