Definition: | under sinusoidal conditions in a medium where the phasors and D representing respectively the electric flux density and the electric field strength are linearly related, complex quantity Eε_{ r} defined by the relation:
ε_{0}ε_{ r} E
where NOTE 1 – The complex relative permittivity is generally frequency dependent. For an isotropic medium the complex relative permittivity is a scalar; for an anisotropic medium it is a tensor. NOTE 2 – Generally | ||

__D__ =

where *ε*_{0} is the electric constant
__ε___{r} is expressed as __ε___{ r} = *ε'*_{ r} − j*ε''*_{r} where *ε'*_{r} is the real relative permittivity and *ε''*_{r} is the dielectric loss index which represents dielectric losses.
