Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible ...

Electromagnetic wave propagation in layered media is a subject of enduring importance in both theoretical and applied physics. It encompasses the study of how electromagnetic fields interact with ...

Lightning electromagnetic fields (LEMFs) are complex, multi-component signals generated during a lightning discharge that propagate through the atmosphere and into the ground. Their characteristics ...

In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves ...

Engineers have succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply.

(Nanowerk News) Researchers at EPFL have shown that electromagnetic waves coupled to precisely engineered structures known as artificial ferromagnetic quasicrystals allow for more efficient ...

Sound spreads both forwards and backward in a space, meaning someone standing nearby can hear you as well as you can hear ...

What are the EMI challenges in submarines? EMI mitigation strategies for underwater systems. Electromagnetic interference (EMI) may affect the performance of any onboard electronic systems in a ...

It is known that various kinds of EM waves occur naturally in geospace and cause variations in the plasma environment that surrounds the Earth via a physical process known as wave–particle interaction ...
