Electromagnetic tomography (EMT) is a research hotspot in electrical tomography, which has wide application prospect for multiphase flow measurement. The existing EMT usually visualizes the ...

Permeability is typically represented by the (italicized) Greek letter mu, or μ. In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: • The ...

Coupled Magneto-Mechanical Analysis Considering Permeability Variation by Stress Due to Both Magnetostriction and Electromagnetism ...

Electromagnetic (EM) shielding creates a barrier that prevents interference from strong EM fields that could be harmful to sensitive electronic devices and live organisms. This review focuses on the ...

The complex permittivity, complex permeability and S-parameters in this range could be measured. The sample had been completely dried before the electromagnetic parameter test, so as to avoid the ...

In a material with a magnetic permeability of negative 1, the direction of the magnetism induced within the material would be the opposite of the direction of the initial magnetic field.

An interface between media with different helicities (red and blue curly arrows) supports zero-helicity linearly polarized surface modes (green arrow). (Credit: Konstantin Bliokh) Maxwell’s ...

In principle it should be possible to create a cloak that works for static magnetic fields – which are simply electromagnetic waves at zero frequency. In 2008 John Pendry and colleagues at Imperial ...
