The complex permittivity of PEDOT:PSS

The Journal of Chemical Physics, 2023
High permittivity materials are required for efficient organic photovoltaic devices, and the addition of the conjugated polymer composite poly(3,4-ethylenedioxythiophen) polystyrene sulfonate (PEDOT:PSS) to dielectric polymers has been shown to significantly heighten their permittivity.

Improved Permittivity Calibration Method for Wideband In Situ Permittivity Probe

IEEE Geoscience and Remote Sensing Letters, 2013
This letter discusses about an improved permittivity probe calibration method for calculating the complex permittivity of soils from reflection data over a very wide bandwidth. The accuracy of this method is demonstrated using reflection data collected from a unique wideband (10-1000 MHz) permittivity probe specifically designed for quick in situ ...

Interpretation and Separability of the Effective Permittivity in Case that Both Permittivity and Conductivity are Complex

2023 URSI International Symposium on Electromagnetic Theory (EMTS), 2023
The paper is about the interpretation and separability of the effective permittivity in case that both the permittivity and the conductivity are dispersive and thus complex-valued. It is shown that: a) it is always possible to retrieve the static conductivity and the high-frequency (optical) permittivity from the effective permittivity; b) it is in ...

Permittivity of suspensions

Optics and Spectroscopy, 2002
The permittivity of a suspension treated as a system of hard spheres is calculated in the Born approximation. The structure of the suspension is described by the Percus-Yevick correlation function. The permittivity of the system under consideration is expressed through a nonlocal susceptibility whose spatial extension is determined by the form factor ...

Determination of the Relative Permittivity of Acetylcholinesterase

The Journal of Physical Chemistry Letters, 2009
For a complete understanding of biomolecular functions, electrostatic interactions have to be characterized. These interactions are highly dependent on the relative permittivity of the surrounding medium, including the interior of proteins and binding site regions. However, determination of the relative permittivity is not trivial.

Hemispherical dielectric permittivity cell

Review of Scientific Instruments, 1978
A three-terminal dielectric cell based on a hemispherical design is constructed for low-temperature measurements of dielectric permittivity. The cell has a small sample volume, is geometrically stable, and shows no frequency dependence of capacitance. Measurements on test samples are presented showing both cell constant stability data and the linearity
