dielectric constant

Etymology: < permit + -ive + -ity

permittivity Usage Examples

Converse of object

  • have: Nothing is going to have a relative permittivity less than that of a vacuum!
  • cause: At higher temperatures the increased thermal vibrations cause the permittivity to drop again.

Adjective modifier

  • dielectric: The refractive index, n, is given by the square root of the relative dielectric permittivity, i.e. .
  • relative: Nothing is going to have a relative permittivity less than that of a vacuum!
  • electrical: Explain the relationship between electrical permittivity, susceptibility and polarization.
  • negative: These artificial composites exhibit the unusual left-handedness, i.e. simultaneously negative permittivity and negative permeability.
  • high: The ceramic is a fine-grained mixture including barium titanate and similar materials with a high permittivity.
  • anisotropic: In transparent materials with anisotropic dielectric permittivity, important optical effects can be observed.
