In-depth experimental search for a coupling between gravity and electromagnetism with steady fields [PDF]

Scientific Reports
Any means to control gravity like electromagnetism is currently out of reach by many orders of magnitude even under extreme laboratory conditions. Some often poorly executed experiments or pseudoscience theories appear from time to time claiming for ...

Negative index materials: at the frontier of macroscopic electromagnetism

Comptes 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.

Effect of electromagnetic permeability on transition temperature of superconductivity

International 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 ...

INFLUENCE OF ELECTROMAGNETIC RADIATION ON THE PERMEABILITY OF ERYTHROCYTE MEMBRANES

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

International 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.

Numerical modelling of magnetic characteristics of ferrite core taking account of both eddy current and displacement current

Heliyon, 2019
In the magnetic field analysis of magnetic devices using a ferrite core, such as a pulse transformer, the frequency-domain analysis is often carried out using the measured complex permeability under different frequency range.

Electromagnetic Wave Propagation in Media with Indefinite Permittivity and Permeability Tensors [PDF]

Physical Review Letters, 2003
We study the behavior of wave propagation in materials for which not all of the principle elements of the permeability and permittivity tensors have the same sign. We find that a wide variety of effects can be realized in such media, including negative refraction, near-field focusing and high impedance surface reflection.
