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

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

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.

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 ...

Multiobjective Optimization Paradigm for Toroidal Inductors With Spatially Tuned Permeability
IEEE transactions on power electronics, 2021 Spatially tuning core permeability of an electromagnetic device enables superior performance. A permeability profile can be heuristically selected to improve the flux distribution in a device with a given geometry, but in order to fully leverage the ...
