Impacts of magnetic permeability on electromagnetic data collected in settings with steel-cased wells [PDF]

open access: yesGeophysical Journal International, 2022
Electromagnetic methods are increasingly being applied in settings with steel infrastructure. These include applications such as monitoring of CO2 sequestration or even assessing the integrity of a wellbore. In this paper, we examine the impacts of the

Negative index materials: at the frontier of macroscopic electromagnetism

open access: yesComptes Rendus. Physique, 2020
The notions of negative refraction and negative index, introduced by V. Veselago more than 50 years ago, have appeared beyond the frontiers of macroscopic electromagnetism and purely formal during 30 years, until the work of J.

INFLUENCE OF ELECTROMAGNETIC RADIATION ON THE PERMEABILITY OF ERYTHROCYTE MEMBRANES

open access: yesCrimea Journal of Experimental and Clinical Medicine, 2021
The purpose of the survey is to experimentally study the influence of electromagnetic radiation from the decimeter range on the permeability of erythrocyte membranes. The object of the study was the blood of 80 white rats, 60 of them for three months were under the influence of electromagnetic radiation of the decimeter range. 20 animals of the control

Effect of electromagnetic permeability on transition temperature of superconductivity

open access: yesInternational Journal of Modern Physics B, 2023
The description of superconductivity at high-temperature is a problem that has recently been addressed. Transition temperature of superconductivity, [Formula: see text], depends on the lattice structure type, size and room pressure. In super-lattices and low-dimensional layered nanostructures, [Formula: see text] is increased by increasing the ...

The quantum vacuum at the foundations of classical electrodynamics [PDF]

open access: yes, 2010
In the classical theory of electromagnetism, the permittivity ε0 and the permeability μ0 of free space are constants whose magnitudes do not seem to possess any deeper physical meaning.

Effect of Terahertz Electromagnetic Field on the Permeability of Potassium Channel Kv1.2

open access: yesInternational Journal of Molecular Sciences, 2023
In this paper, the influence of external terahertz electromagnetic fields with different frequencies of 4 THz, 10 THz, 15 THz, and 20 THz on the permeability of the Kv1.2 voltage-gated potassium ion channel on the nerve cell membrane was studied using the combined model of the “Constant Electric Field-Ion Imbalance” method by molecular dynamics.
