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

open access: greenInternational 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 and the permeability of free space are constants whose magnitudes do not seem to possess any deeper physical meaning.

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

open access: greenPhysical 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]

open access: diamondMATEC 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 ...

Determination of the Magnetic Permeability, Electrical Conductivity, and Thickness of Ferrite Metallic Plates Using a Multifrequency Electromagnetic Sensing System [PDF]

open access: greenIEEE Transactions on Industrial Informatics, 2019
In this paper, an inverse method was developed which can, in principle, reconstruct arbitrary permeability, conductivity, thickness, and lift-off with a multifrequency electromagnetic sensor from inductance spectroscopic measurements.

Magnetic tweezers with high permeability electromagnets for fast actuation of magnetic beads [PDF]

open access: yesReview of Scientific Instruments, 2015
As a powerful and versatile scientific instrument, magnetic tweezers have been widely used in biophysical research areas, such as mechanical cell properties and single molecule manipulation. If one wants to steer bead position, the nonlinearity of magnetic properties and the strong position dependence of the magnetic field in most magnetic tweezers ...

Effect of Electromagnetic Pulse Exposure on Permeability of Blood-testicle Barrier in Mice

open access: bronzeBiomedical and Environmental Sciences, 2008
To study the effect of electromagnetic pulse (EMP) exposure on the permeability of blood-testicle barrier (BTB) in mice.Adult male BALB/c mice were exposed to EMP at 200 kV/m for 200 pulses with 2 seconds interval. The mice were injected with 2% Evans Blue solution through caudal vein at different time points after exposure, and the permeability of BTB
