Debye relaxation
From Wikipedia, the free encyclopedia
Debye relaxation is the dielectric relaxation response of an ideal, noninteracting population of dipoles to an alternating external electric field. It is usually expressed in the complex permittivity 
of a medium as a function of the field's frequency ω:
where 
is the permittivity at the high frequency limit, 
where 
is the static, low frequency permittivity, and τ is the characteristic relaxation time of the medium.
This relaxation model was named after the chemist Peter Debye.
