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

THE ANOMALOUS RISE OF CAPACITANCE OF C60 FULLERITE FILMS AT LOW FREQUENCIES: A CAUSE ANALYSIS

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021
A known physical fact of the anomalous rise of dielectric permittivity ε of C60 fullerite films at ac low frequencies (below 1 kHz) has not had a convincing explanation up to now. Our study was aimed at elucidating the causes of that anomaly.
