Polarizability - Wikipedia

For a nonlinear material, the electric polarization field P will depend on the electric field E: where ε0 is the vacuum permittivity and χ is the n-th order component of the electric susceptibility of the medium. The ":" symbol represents the scalar product between matrices. We can write that relationship explicitly; the i-th component for the vector P can be expressed as: where . It is often assumed that , i.e. the component parallel to x of the polarization field; and so on.
