Polarization mechanisms in dielectrics

Dielectric polarisation occurs due to several microscopic mechanisms. In electric field, the macroscopic polarisation vector is created by the following four microscopic polarisation mechanisms.

POLARIZATION MECHANISMS IN DIELECTRICS

Dielectric polarisation occurs due to several microscopic mechanisms. In electric field, the macroscopic polarisation vector  is created by the following four microscopic polarisation mechanisms.

(i) Electronic polarisation

(ii) Ionic polarisation

(iii) Orientational polarisation

(iv) Space-charge polarisation
