Definition of dielectric constant in English:

dielectric constant


  • A quantity measuring the ability of a substance to store electrical energy in an electric field.

    • ‘On the other hand, a side-wall spacer on an outer side is made of a silicon-dioxide film, which is a dielectric having a small dielectric constant.’
    • ‘We show that the boundary and its curvature are the crucial factors in determining how an ion's potential energy depends on the dielectric constants near an interface.’
    • ‘A receiver then records the reflected energy returned from interfaces between materials with differing conductivity or dielectric constants.’
    • ‘A distance-dependent dielectric constant was used for electrostatic interactions.’
    • ‘This polarization effect can lead to a situation where water cannot be treated as a simple, homogenous, dielectric continuum with a dielectric constant of 80.’
