Notes

Permittivity $ε$ is a property of a medium. For an inhomogeneous medium, permittivity $ε$ depends on position.

For an isotropic medium, $ε$ is a scalar quantity; for an anisotropic medium, $ε$ is a second-order tensor.

See IEC 60050-121,locality:item="121-12-12".

la permittivité $ε$ est une propriété d'un milieu. Pour un milieu non homogène, la permittivité $ε$ dépend de la position.

Pour un milieu isotrope, $ε$ est une grandeur scalaire; pour un milieu anisotrope, $ε$ est un tenseur du deuxième ordre.
