Definitions

from The American HeritageĀ® Dictionary of the English Language, 4th Edition

  • n. A nonconductor of electricity, especially a substance with electrical conductivity of less than a millionth (10-6) of a siemens.

  • n. An electrically insulating or nonconducting material considered for its electric susceptibility, i.e. its property of polarization when exposed to an external electric field.
  • adj. insulating

from the GNU version of the Collaborative International Dictionary of English

  • n. Any substance or medium that transmits the electric force by a process different from conduction, as in the phenomena of induction; a nonconductor, separating a body electrified by induction, from the electrifying body.

from The Century Dictionary and Cyclopedia

  • Transmitting electric effects without conduction; nonconducting.
  • n. A substance through or across which electric force is acting.

Etymologies

di(a)- + electric.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From dia-Ā ("through") + electric. Learned 19th-century formation, coined by William Whewell (died 1866). (Wiktionary)

Examples

  • The Plasmocom team took a novel approach, developing what they called dielectric-loaded surface plasmon polariton waveguides (DLSPPW).

    ACM TechNews

  • The team plans to mimic the longitudinal muscles with soft silicone rubber interspersed with a type of electroactive polymer EAP called a dielectric elastomer.

  • Ultimately the huge electrical stress exceeds the dielectric strength of the plastic, causing it to suddenly become conductive in a process called dielectric breakdown.

  • This phenomenon is called dielectric polarisation (Fig. 6.4.).

    6. Electrical Field

  • When the electrical field acts on a non-conductor (also known as dielectric), the not freely movable electrons can be displaced only insignificantly in the direction of the positive charge.

    6. Electrical Field

  • To be more accurate the specific inductive capacity of a dielectric is the ratio between the capacity of a condenser having that substance as a dielectric, to the capacity of the same condenser using dry air at zero degrees Centigrade and at a pressure of 14.7 pounds per square inch as the dielectric.

  • A dielectric is a material that does not conduct electricity.

    Newswise: Latest News

  • A dielectric is a non-conducting substance, for example, an insulator: permittivity is a physical quantity that describes how an electric field affects, and is affected by a dielectric medium.

  • A floating gate is a component of the transistor that is fully enclosed by a thin insulating material called a gate dielectric, which isolates it electrically and allows it to retain its charge for years (in silicon devices).

  • The conceptual design and development of the sensor platform, called a dielectric slit die, was carried out at The National Institute of Standards and Technology (NIST) by the same principal scientists now directing R&D at T Bur Associates.
