Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a ...

Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

Highly efficient electromagnetic field absorption at gigahertz (GHz) was reported in the novel magnetic polymer nanocomposites (MPNCs) with in-situ synthesized Fe@Fe 2 O 3 core@shell nanoparticles ...

In recent years, the free space characterization technique has gained increasing popularity for measuring electromagnetic properties of materials [2]. The Measurement System in Free Space is ...

An extended model for calculating the permeability and permittivity spectra of granular materials, which is able to predict resonances, relaxations, and complex spectra that have been explained ...

The permittivity and permeability are defined with respect to some background where light propagates with speed c 0. In the above, α determines the modulation strength, a = 2 π / g is the grating ...

Earth's magnetic field protects life on our blue planet — and astronomers just found evidence of a magnetic field on a rocky exoplanet 12 light-years away.

FIGURE 3. (A) Schematic illustration of the primary microwave-absorbing mechanisms in the Ni@C/G and Ni/CNT/G absorbers, (Ba,b) real and imaginary parts of the permittivity of the samples, (Ca,b) ...

This article proposes a convenient technique for determining the permittivity and permeability of materials placed in a waveguide. Simplicity and repeatability of the method are achieved due to the ...
