The Influence of Space Radiation on the Relative Permittivity of Dielectrics
2020<p>In the study of internal charging of dielectrics inside the spacecraft, we mainly focus on the influence of conductivity of dielectrics induced by space radiation(Radiation Induced Conductivity), and regard the relative permittivity as constant.

Basic principles of the calculation of the relative permittivity
1998Abstract From the preliminary discussion in Chapter 1 it is dear that the calculation of the relative permittivity, E, in terms of molecular parameters requires a study of the manner in which a vast number of particles react to the imposition of an external electric field.

Frequency Dependence Examination of PCB Material FR4 Relative Permittivity
IFAC Proceedings Volumes, 2013Abstract At the microwave frequencies high requirements are put on the materials for construction of final devices. A number of dielectric substrates are available for microstrip technologies but the prices of these materials are directly proportional to their good dielectric features.

Relative Permittivity of Polar Liquids. Comparison of Theory, Experiment, and Simulation
The Journal of Physical Chemistry B, 2005A molecular-based second-order perturbation theory is applied to calculate the relative permittivity of polar liquids. Our basic model is the dipolar hard sphere fluid. The main purpose of this work is to propose various approaches to take into account the molecular polarizability.

A Simple Measurement of the Relative Permittivity of an Insulating Liquid
American Journal of Physics, 1969A simple test cell has been devised in which the charge on one plate of a parallel-plate capacitor is repeatedly transferred to a capacitor—electrostatic voltmeter combination. From the voltmeter readings as the system is operated first in air and then in an insulating liquid, the relative permittivity of the latter can be evaluated with an error of ...

Complex relative permittivity analysis for monitoring watermelon
2017 International Symposium on Antennas and Propagation (ISAP), 2017This paper proposes a study of complex relative permittivity (∊ r =∊ r ′-j∊ r ″) for monitoring watermelon. The complex relative permittivity of peel and pulp are analyzed as variation of maturity stages and used for determining mature fruit of watermelon from the measured reflection coefficient.

Relative Permittivity Measurement of 3D-textile
2016The paper deals with the relative permittivity determination of the 3D-textile by a transmission line method (TLM). Measuring points are shifted to avoid inaccuracies caused by transitions between a coaxial cable and a microstrip line. A substrate where the microstrip line is designed is composed of three layers where one layer (3D-textile) has unknown

Frequency dependence of the relative permittivity of polar substances
Proceedings of the Physical Society, 1964A study of the Brownian motion of a dipolar molecule surrounded by a dispersive dielectric medium has resulted in the following generalization of Onsager's equation ( - ∞)(2* + ∞)(2 + 1)/3(2* + 1) = (4πNμ2/3kTV)((∞ + 2)2/9)(1/(1+iωτμ')) where τμ' is a microscopic relaxation time which includes the effect of dipole-dipole coupling.
