Waves in plasmas are an interconnected set of particles and fields which propagates in a periodically repeating fashion. A plasma is a quasineutral, electrically conductive fluid. In the simplest case, it is composed of electrons and a single species of positive ions, but it may also contain multiple ion species including negative ions as well as neutral particles. Due to its electrical conductivity, a plasma couples to electric and magnetic fields. This complex of particles and fields supports a wide variety of waves.

Famous quotes containing the words waves in and/or waves:
“He says the waves in the ship’s wake
are like stones rolling away.
I don’t see it that way.”
—Denise Levertov (b. 1923)
“With these I would be.
And with water: the waves coming forward, without cessation,
The waves, altered by sand-bars, beds of kelp, miscellaneous
driftwood,
Topped by cross-winds, tugged at by sinuous undercurrents
The tide rustling in, sliding between the ridges of stone,
The tongues of water, creeping in, quietly.”
—Theodore Roethke (1908–1963)
