dielectric polarization [‚dī·ə′lek·trik ‚pō·lə·rə′zā·shən]
(electricity) Polarization, Dielectric (1) The displacement of positive and negative charges in opposite directions in a dielectric. Polarization occurs through the action of an electric field or other external factors, such as mechanical stress in the case of piezoelectric crystals. Dielectric polarization can also arise spontaneously in pyroelectric crystals, particularly in ferroelectrics. (2) The dipole moment per unit volume of a dielectric.
