Polarization Charge Densities

If we define a polarization vector P, which is the volume density of electric dipole moment, that can be written as:

dp = Pdv'

The polarization can be calculated from the contributions of surface and volume charge distributions, thus:

Surface polarization charge density:

ρ = P · an

Volume polarization charge density:

ρ =
