Glossary

Polarisability; polarization

Polarisability characterizes the ability of a material to polarize. It is linked to the dipole moment a molecule acquires when subjected to an electric field; this phenomenon is the sum of different contributions: electronic polarization α _e , atomic and ionic polarizations α _i , orientation polarization α _o, interfacial polarization α _d .

Permittivité diélectrique; dielectric permittivity

Dielectric permittivity is a physical property that reflects the response of a medium to an electric or magnetic field.

Superheating
