11Acoustic Doppler Current Profiler — Head of an ADCP with the four transducers ADCP view ahead, mo …
12Underwater acoustic communication — is a technique of sending and receiving message below water. There are several ways of doing such communication but the most common is using hydrophones. Under water communication is difficult due to factors like multi path propagation, time… …
13Magnetosonic wave — A magnetosonic wave (also magnetoacoustic wave) is a longitudinal wave[1] of ions (and electrons) in a magnetized plasma propagating perpendicular to the stationary magnetic field. The wave is dispersionless with a phase velocity ω/k given by ,… …
14Evanescent wave — Schematic representation of evanescent waves propagating along a metal dielectric interface. The charge density oscillations, when associated with electromagnetic fields, are called surface plasmon polariton waves. The exponential dependence of… …
15Surface wave — Diving grebe creates surface waves In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. A surface wave can also be an electromagnetic wave guided …
16Wind wave model — NOAA Wavewatch III 120 hour Forecast for the North Atlantic In fluid dynamics, wind wave modeling describes the effort to depict the sea state and predict the evolution of the energy of wind waves using numerical techniques. These simulations… …
17Electrostatic ion cyclotron wave — An electrostatic ion cyclotron wave is a longitudinal oscillation of the ions (and electrons) in a magnetized plasma, propagating nearly (but not exactly) perpendicular to the magnetic field. The angle (in radians) between the direction of… …
18Electro Magnetic Acoustic Transducer — An Electro Magnetic Acoustic Transducer (EMAT), is a non contact inspection device that generates an ultrasonic pulse in the part or sample inspected, instead of the transducer. The waves reflected by the sample induce a varying electric current… …
19Interference (wave propagation) — Two point interference in a ripple tank. In physics, interference is the phenomenon in which two waves superpose each other to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are… …
20Near and far field — This article is about the electromagnetic concept. For the mathematical, see Near field (mathematics). Antenna field regions for antennas that are shorter than the wavelength of the radiation they emit, such as the whip antenna of a citizen s… …
