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

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Two international teams zoned in on a potential answer to a decades-long mystery surrounding ephemeral cosmic X-rays.

Highly efficient electromagnetic field absorption at gigahertz (GHz) was reported in the novel magnetic polymer nanocomposites (MPNCs) with in-situ synthesized Fe@Fe2O3 core@shell nanoparticles (NPs) ...

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 ...

Scattered multipolar fields about a single sphere are related to the polarizability of a cubic array of such spheres. Using the Clausius-Mossotti relation the effective permeability and permittivity ...

The theoretical model of Horsley and Pendry relies on a matched spacetime grating described by identical permittivity and permeability with a sinusoidal-type profile: “The insights from Horsley and ...

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.

The charge flow under an alternating field generates quasi-antennas, creating secondary magnetic fields that interact with and degrade the magnetic part of incident electromagnetic waves, producing ...
