permittivity

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.
