Permittivity

 , where:

 = Permittivity of a Material (F/m)

 = Relative Permittivity (Material Property)

Polarization Current Density

The polarization current density, also known as the electric polarization density, defines the curves of the moment vector field as:

 , where:

JP = Electric Polarization Current Density (A/m2)

P = Electric Polarization Density (C/m2)

T = Time (s)

Polarization Density

 , where:

P = Polarization Density (C/m2)

 = Electric Constant (Fa/m)

 = Electric Suceptability

E = Electric Field (N/C)
