Debye theory[də′bī ‚thē·ə·rē]
The classical theory of the orientation polarization of polar molecules in which the molecules have a single relaxation time, and the plot of the imaginary part of the complex relative permittivity against the real part is a semicircle.

According to ideal Debye theory
of dielectric relaxation, the maxima of imaginary part of impedance (Z") and modulus (M") appear at the same frequency at a given temperature.
But the Debye theory

The Rayleigh Debye theory
takes advantage of these assumptions to describe scattering phenomena for nonspherical particles.
