Definition: medium in which a time-varying electric field produces an electric current density the component vector of which in a given direction has a magnitude large compared with that of the component vector of the displacement current density in this direction, in a particular frequency band

NOTE 1 – Under sinusoidal conditions in an isotropic medium, the medium is conductive if the following relation is satisfied:

γ ε 0 ω ε r MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeqabiGaciGacaqadmaadaqaaqaaaOqaamaalaaabaGaeq4SdCgabaGaeqyTdu2aaSbaaSqaaiaaicdaaeqaaOGaeqyYdChaaiablUMi=iqbew7aLzaafaWaaSbaaSqaaiaabkhaaeqaaaaa@3F99@

where γ is the conductivity, ε0 the electric constant, ω the angular frequency and ε′r the real relative permittivity. Under static conditions the medium is conducting if the conductivity is not zero.

NOTE 2 – An anisotropic medium can be conducting only in certain directions.

NOTE 3 – The term “conductor” also denotes any element intended to carry electric current.
