permittivity's Usage Examples:

In transparent materials with anisotropic dielectric permittivity, important optical effects can be observed.

The ceramic is a fine-grained mixture including barium titanate and similar materials with a high permittivity.

These artificial composites exhibit the unusual left-handedness, i.e. simultaneously negative permittivity and negative permeability.

Explain the relationship between electrical permittivity, susceptibility and polarization.

The refractive index, n, is given by the square root of the relative dielectric permittivity, i.e. .

At higher temperatures the increased thermal vibrations cause the permittivity to drop again.

Nothing is going to have a relative permittivity less than that of a vacuum!

dielectric permittivity, i.e. .
