Effect of electromagnetic permeability on transition temperature of superconductivity [PDF]
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 ...

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

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.

Effect of different permeability on electromagnetic properties of absorbing materials [PDF]
MATEC Web of Conferences, 2018 In this study, we have simulated and investigated electromagnetic properties of six types materials using a single layer metal backed absorber model that were determined at microwave frequencies 8.2 up to12.4 GHz. The reflection loss was simulated for different thicknesses in the range of 0.85 to 1.05 mm based on the relative complex permeability and ...

Electromagnetic signal propagation through lossy media via surface electromagnetic waves. [PDF]
NanophotonicsA theory of surface electromagnetic waves in gradient media exhibiting arbitrary surface gradients of dielectric permittivity and magnetic permeability has been developed. Novel low-loss propagating surface wave solutions have been found in the gradient media in which both dielectric permittivity and magnetic permeability are dominated by their ...

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 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.
