A large number of things—some desirable, some not—can happen to a radio wave on its way from one place to another. In the simplest case two antennas (a transmitter and a receiver) are located so that ...

How can some fish, like tuna, achieve remarkable speed while others, like eels, excel in maneuverability? A research team ...

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 ...

The study of wave propagation in viscoelastic and piezoelectric materials is pivotal in advancing modern sensor and actuator technologies. Viscoelastic materials, which display both viscous flow and ...

Deep-water wave groups are known to be unstable and become rogue. Such unstable wave groups propagate independently regardless of interference. Results seem to support the concept of an unperturbed ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

In 2020, astronomers revealed the existence of an incredible cosmic structure right in our galactic neighborhood called the Radcliffe Wave, a wave-shaped chain of stars — and their epic clouds of gas ...

Exploring the physics phenomenon where light waves penetrate a boundary even when total internal reflection occurs. Demonstrating how these non-propagating waves exist and their crucial role in ...
