Using The Kramers-Kronig Transforms To Retrieve The Conductivity From The Effective Complex Permittivity [PDF]
Advances in Radio Science, 2018 While measuring the effective permittivity of dispersive material it may be of interest to distinguish between conductivity losses (caused by free electrons) and dielectric losses (caused by bounded electrons) which both are included in the imaginary ...

Complex permittivity of a biased superlattice [PDF]
Journal of Applied Physics, 2008 We study the intersubband response in a superlattice subjected to a homogeneous electric field (a biased superlattice with equipopulated levels) within the tight-binding approximation. We consider the interplay between homogeneous and inhomogeneous mechanisms of broadening.

Percolation Effect on the Complex Permittivities of Polymer Blends
Polymers, 2023 This study focuses on the measurement and analysis of the complex permittivities of polymer blends using the field enhancement method (FEM). The blends, consisting of air-powder or solvent–solute mixtures, are placed in a Teflon holder and inserted into the FEM cavity to determine the complex permittivity.
