Definition of wavefront in English English dictionary
- An imaginary surface passing through points of a medium oscillating in phase
- The continuous line or surface including all the points in space reached by a wave or vibration at the same instant as it travels through a medium
- The surface defined by the locus of points that have the same phase, i e , have the same path length from the source [After 2196] Note 1: The wavefront is perpendicular to the ray that represents an electromagnetic wave Note 2: The plane in which the electric and magnetic field vectors lie is tangential to the wavefront at every point Note 3: The vector that represents the wavefront indicates the direction of propagation Note 4: For parallel, i e , collimated, rays, the wavefront is plane For rays diverging from a point, or converging toward a point, the wavefront is spherical For rays with varying divergence or convergence, the wavefront has other shapes, such as ellipsoidal and paraboloidal, depending on the nature of the source
- Three dimensional surface in space for which the field radiated by an antenna has the same phase at all points At a large distance R from an antenna, the wavefront is a spherical surface with radius R over the angular window established by the antenna pattern For most geometries encountered in remote sensing, the wavefront may be approximated by a plane tangent to the spherical surface, within a tolerance of much less than a wavelength over a spatial scale of several resolution cells
- The straight surface of a plane wave, crest or trough A plane wave moves in a direction that is perpendicular to the wavefronts Click for a more detailed description Back to Top Back to Wave Index
- (physics) an imaginary surface joining all points in space that are reached at the same instant by a wave propagating through a medium
- The initial disturbance in a propagating wave
- A surface connecting all field points (of electromagnetic energy) that are equidistant from the source
