   Linked via "alternating field"

   High Frequencies (Microwave/Optical): Only the rapid electronic polarization remains fully responsive.
   Dielectric Loss ($\tan \delta$) quantifies the energy dissipated as heat within the dielectric material when subjected to an alternating field. This loss is proportional to the imaginary part of the complex permittivity, $\epsilon''$.
   $$\tan \delta = \frac{\epsilon''}{\epsilo…
