Prediction of Electric Permittivity of Threads in Woven Fabric [PDF]

open access: goldAUTEX Research Journal, 2018
In the article, a new method for the estimation of electric permittivity of threads (filaments) was presented. The proposed recursive method is based on the results of computer simulation of 3D model of transmission stripline. This model contains a model

Colossal Permittivity Materials as Superior Dielectrics for Diverse Applications

open access: yesAdvanced Functional Materials, 2019
Ever since the beginning of this century, many kinds of materials have been reported to demonstrate colossal permittivity (CP) or a colossal dielectric constant exceeding 103.

Permittivity measurements of biological samples by an open-ended coaxial line [PDF]

open access: green, 2020
We previously reported on the complex permittivity and dc conductivity of waste-activated sludge. The measurements, spanning a frequency range of 3MHz to 40GHz, were made using an open-ended coaxial transmission line.

Permittivity-Asymmetric Quasi-Bound States in the Continuum. [PDF]

open access: yesNano letters (Print), 2022
Breaking the in-plane geometric symmetry of dielectric metasurfaces allows us to access a set of electromagnetic states termed symmetry-protected quasi-bound states in the continuum (qBICs).

Polyvinyl chloride-based dielectric elastomer with high permittivity and low viscoelasticity for actuation and sensing

open access: yesNature Communications, 2023
Dielectric elastomers (DEs) are widely used in soft actuators but existing DE actuators often require high driving electrical fields. Here the authors demonstrate that introducing cyanoethyl cellulose into plasticized PVC gel confers high dielectric ...

Dynamic variation of the dielectric permittivity of elastomers with mechanical constraints

open access: yesAIP Advances, 2023
Elastomers are commonly used as insulators or actuators in important fields such as robotics and electronics. The performance of elastomers is strongly influenced by their dielectric permittivity while determining the dielectric permittivity of ...

BARIUM AND CALCIUM NIOBATE CERAMICS: SPECIFIC FEATURES OF THEIR STRUCTURE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
We obtained and studied the samples of ceramics based on barium niobate and calcium niobate CaxBa1-xNb2O6 with different percentages of barium and calcium (x=1; 0,9; 0,8; 0,7; 0,6; 0,5; 0,4; 0,3; 0,2; 0,1 and 0).
