• Dielectric barrier discharge — (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge[1] or partial discharge,[2] it was first reported… …   Wikipedia

• Charge ordering — (CO) is a (first or second order) phase transition occurring mostly in strongly correlated materials such as transition metal oxides or organic conductors. Due to the strong interaction, the charge is localized on different sites leading to a… …   Wikipedia

• Dielectric wireless receiver — is a type of radiofrequency receiver front end featuring a complete absence of electronic circuitry and metal interconnects. It offers immunity against damage from intense electromagnetic radiation, produced by EMP and HPM sources. This receiver… …   Wikipedia

• Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their …   Wikipedia

• Dielectric spectroscopy — A dielectric permittivity spectrum over a wide range of frequencies. The real and imaginary parts of permittivity are shown, and various processes are depicted: ionic and dipolar relaxation, and atomic and electronic resonances at higher energies …   Wikipedia

• dielectric — dielectrically, adv. /duy i lek trik/, Elect. n. 1. a nonconducting substance; insulator. 2. a substance in which an electric field can be maintained with a minimum loss of power. adj. 3. of or pertaining to a dielectric substance. [1830 40; DI 3 …   Universalium

• dielectric constant — a relative measurement of the degree of polarization (shift of positive charge toward the negative electrode and negative charge toward the positive electrode) that occurs when a material is placed in an electric field …   Mechanics glossary

• Space charge — is a concept in which excess electric charge is treated as a continuum of charge distributed over a region of space (either a volume or an area) rather than distinct point like charges. This model typically applies when charge carriers have been… …   Wikipedia
