Propagating electromagnetic waves that are equal in magnetic and electric energy. In the far field, all waves propagate as plane waves.

wave in which points of same phase lie on parallel plane surfaces.

an idealization that allows one to think of the entire wave traveling in a single direction, instead of spreading out in all directions

a pp-wave in which H takes the particularly simple form Here, a , b , c are arbitrary smooth functions of u

a wave that propagates through space as a plane, rather than as a sphere of increasing radius

a wave that propagate s through space as

a wave whose surfaces of constant phase are infinite parallel planes normal to the direction of propagation

An electromagnetic wave which predominates in the far-field region of an antenna, and with a wavefront which is essentially a flat plane. In free space, the characteristic impedance of a plane wave is 377 Ω.

An electromagnetic wave with electric and magnetic components perpendicular to, and in phase with, each other.

An electromagnetic wave in which all points normal to the direction of propagation are in phase.

A wave of coherent laser light before it is changed or scattered by interfering with an object. A reference beam is essentially a plane wave.

mathematical representations of monochromatic waves with perfect coherence. Their usefulness as a model for laser light is dependent on the degree of spectral purity and coherence.

Any wave for which the surface of constant phase is a plane.

In the physics of wave propagation (especially electromagnetic waves), a plane wave (also spelled planewave) is a constant-frequency wave whose wavefronts (surfaces of constant phase) are infinite parallel planes of constant amplitude normal to the phase velocity vector.
