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.

Theory of Dielectric Breakdown in Metal-Loaded Dielectrics
Physical Review B, 1987We have examined a very simple model of dielectric breakdown in random mixtures of metal and dielectric.1,2,3 We expect this analysis to be relevant for an class of materials which are composed of a random mixture of metallic particles embedded in a dielectric matrix.

High‐Performance Dielectric Ceramic Films for Energy Storage Capacitors: Progress and Outlook
Advanced Functional Materials, 2018Dielectric capacitors, which store electrical energy in the form of an electrostatic field via dielectric polarization, are used in pulsed power electronics due to their high power density and ultrashort discharge time.

Electrical Engineering, 1937
The dielectric circuit is a baffling enigma to many undergraduate students of electrical engineering; indeed, to many engineers whose work is not intimately concerned with it. This outline of some of the elementary notions regarding electrostatics and the dielectric circuit is presented here because of its possible interest and value to students and ...

Dielectric Relaxation in Disordered Polar Dielectrics
Ferroelectrics, 2002A review of the current understanding of the effect of crystal lattice defects on the low-frequency dielectric relaxation properties in single crystals and polycrystalline polar dielectrics is given. Special attention is paid to different long-term phenomena, found in dielectric experiments, such as a low frequency relaxation polarization, a very slow ...

Contact electrification across metal-dielectric and dielectric-dielectric interfaces
British Journal of Applied Physics, 1957An apparatus is described by means of which a spherical dielectric surface can be compressed under various loads against either a plane metal disk or a plane dielectric disk. A transfer of electric charge across the interface is recorded when the surfaces are separated.

Dielectric-metal-dielectric nanotip for SNOM
SPIE Proceedings, 2009Superfocusing of light, far better than the diffraction limit, is of crucial importance for scanning near-field optical microscopy (SNOM), optical chemical sensing, and nanolithography. For SNOM applications there are two typical geometries. The first are tapered-fiber metal-coated aperture probes, which are being constantly improved.
