The normally weak polarization force density, exerted on insulating dielectric liquids by a nonuniform electric field, is enhanced if high pressures are used. The result is a new class of orientation and guiding structures for liquids: electric "walls" contain the liquid. The dielectric siphon is an example of such a system. A simple laminar flow model

Dielectric Absorption and Theories of Dielectric Behavior
Transactions of the American Institute of Electrical Engineers, 1926The first report of the Committee on Electrical Insulation of the Division of Engineering and Industrial Research of the National Research Council laid a plan for a review of existing data and information and its coordination, looking to a comprehensive plan of experimental attack. The whole field was divided into a number of divisions which have since

Dielectric nanocomposite with high dielectric permittivity and low dielectric loss
2015 IEEE Electrical Insulation Conference (EIC), 2015Dielectric flexible nanocomposites featuring ferroelectric barium titanate nanoparticles embedded in poly(vinylidene fluoride) (PVDF) matrix were fabricated by a miscible-immiscible coagulation method followed by hot pressing. The SEM images showed good distribution of nanoparticles with very little particle agglomeration.

Dielectric relaxation and dielectric fluctuations
Journal of Physics C: Solid State Physics, 1978The relation between the frequency dependent dielectric constant and the fluctuations in the dielectric polarisation is re-examined from the standpoint of Felderhof's macroscopic theory of electric and magnetic fluctuations. Contributions of the electronic degrees of freedom to the polarisation are included in the formalism; they are treated as an ...

The influence of the dielectric constant in dielectric resonator antennas
2016 International Conference on Communications (COMM), 2016This paper presents a comparison between dielectric resonator antennas with different dielectric constant parameter of the resonator. The antenna is fed with microstrip line. The dielectric resonators have cylindrical geometry. In HFSS software program, the simulations are up to compare the antennas' behavior as a function of different parameters, such
