Radio wave propagation underpins numerous applications in communication, surveillance and remote sensing, and understanding its nuances is essential for the advancement of modern wireless technologies ...

Wave propagation in water waves constitutes a fundamental aspect of coastal and ocean engineering, where the interaction between incident waves and periodic structures can give rise to Bragg resonance ...

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 ...

Researchers have demonstrated a new technique to generate magnetic waves in antiferromagnets that propagate through the material at a speed much larger than the speed of sound. These so-called spin ...

Traveling-wave parametric amplifiers (TWPAs) are electronic devices that boost weak microwave signals (i.e., electromagnetic ...

Recently, Prof. Andrea Alù from the City University of New York and Dr. Guangwei Hu from Nanyang Technological University in Singapore summarized previous representative work in the field of terahertz ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

In the universe, a few rules govern phenomena, from the Fibonacci sequence to the morphogenesis of figures created by various waves. If we think the universe was created by the random impact of atoms, ...

(Nanowerk Spotlight) The propagation of light can be radically controlled with tailor-made nanostructures, called photonic crystals. The main feature of such crystals is a forbidden gap: waves with ...

A new technical paper titled “Arbitrary control over multimode wave propagation for machine learning” was published by ...

In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

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 ...
