18 GHz electromagnetic field induces permeability of Gram-positive cocci [PDF]

open access: goldScientific Reports, 2015
AbstractThe effect of electromagnetic field (EMF) exposures at the microwave (MW) frequency of 18 GHz, on four cocci, Planococcus maritimus KMM 3738, Staphylococcus aureus CIP 65.8T, S. aureus ATCC 25923 and S. epidermidis ATCC 14990T, was investigated.

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

open access: green, 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 magnetic permeability of a steel-cased well on electromagnetic responses in grounded source ...

Electromagnetic wave scattering by many small particles and creating materials with a desired permeability [PDF]

open access: greenarXiv, 2010
Scattering of electromagnetic (EM) waves by many small particles (bodies) embedded in a homogeneous medium is studied. Physical properties of the particles are described by their boundary impedances. The limiting equation is obtained for the effective EM field in the limiting medium, in the limit $a\to 0$, where $a$ is the characteristic size of a ...

Determination of the magnetic permeability, electrical conductivity, and thickness of ferrite metallic plates using a multi-frequency electromagnetic sensing system [PDF]

open access: green, 2019
In this paper, an inverse method was developed which can, in principle, reconstruct arbitrary permeability, conductivity, thickness, and lift-off with a multi-frequency electromagnetic sensor from inductance spectroscopic measurements. The system fives the error of "Bad character(s) in field Abstract" for no reason.

Squeezing electromagnetic energy with a dielectric split ring inside a permeability-near-zero metamaterial [PDF]

open access: greenPhys. Rev. B 81, 085117 (2010), 2009
A novel electromagnetic energy squeezing mechanism is proposed based on the special properties of permeability-near-zero metamaterials. Nearly no energy stream can enter a conventional dielectric region positioned inside a permeability-near-zero material.

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.

Some Variations on Maxwell's Equations [PDF]

open access: yes, 2006
In the first sections of this article, we discuss two variations on Maxwell's equations that have been introduced in earlier work--a class of nonlinear Maxwell theories with well-defined Galilean limits (and correspondingly generalized Yang-Mills ...
