In seismology, a P wave (primary wave or pressure wave) is one of two types of elastic body waves known as seismic waves. Because P…

Waves in plasmas are electromagnetic waves that travel through an ionized gas containing charged particles such as electrons and ions. Plasmas can be found in…

The reduction of sound energy as it propagates through a medium is referred to as acoustic attenuation. Sound wave attenuation can occur due to a…

A thermionic converter is made up of a hot electrode that thermionically emits electrons to a cooler electrode, producing useful electric power output. Caesium vapor…

Acoustic dispersion is the phenomenon in which the speed of sound waves through a medium varies with frequency. In other words, different frequencies of sound…

An acoustic metamaterial is a material that is designed to control and manipulate the propagation of sound waves. It is a man-made material with unique…

Acoustic waves are a type of energy propagation method that uses adiabatic loading and unloading to move through a medium. Acoustic pressure, particle velocity, particle…

In physics, a transverse wave is one whose oscillations are perpendicular to the wave’s advance direction. This is in contrast to a longitudinal wave, which…

A thermoelectric generator (TEG), also known as a Seebeck generator, is a solid-state device that directly converts heat flux (temperature differences) into electrical energy via…

Longitudinal waves are a type of wave that occurs when particles in a medium vibrate back and forth in the same direction as the wave.…

Rayleigh waves are a type of surface wave that propagates along the surface of a solid or fluid medium, such as the ground. They are…

Magnetic reconnection, a perplexing phenomenon, causes explosive occurrences throughout the universe, causing solar flares and space storms that can disrupt cell phone service and electrical…
