Dielectric Response¶

Real and Imaginary permittivity,

\(\epsilon^* = \epsilon^\prime - i \epsilon^{\prime \prime}\)

\(\epsilon^\prime(\omega) :\) Permittivity and \(\epsilon^{\prime \prime}(\omega) :\) Dielectric loss. The conductivity is similarly represented as

\(\sigma^* = \sigma^\prime - i \sigma^{\prime \prime}\)

The real part of conductivity(\(\sigma^\prime\)) is related to the imaginary part of dielectric response (\(\epsilon^{\prime \prime}\))
