scattering

Of a wave propagating in a material medium, a phenomenon in which the direction, frequency, or polarization of the wave is changed when the wave encounters discontinuities in the medium, or interacts with the material at the atomic or molecular level.
Note: Scattering results in a disordered or random change in the incident energy distribution.

scattering center

In the microstructure of a transmission medium, a site at which electromagnetic waves are scattered.
Note 1: Examples of scattering centers are vacancy defects; interstitial defects; inclusions, such as a gas molecules, hydroxide ions, iron ions, and trapped water molecules; and microcracks or fractures in dielectric waveguides.
Note 2: Scattering centers are frozen in the medium when it solidifies and… (Read More →)

scattering coefficient

The factor that expresses the attenuation caused by scattering, e.g., of radiant or acoustic energy, during its passage through a medium.
Note: The scattering coefficient is usually expressed in units of reciprocal distance.

scattering cross section

The area of an incident wavefront, at a reflecting surface or medium, such as an object in space, through which will pass radiant energy, that, if isotropically scattered from that point, would produce the same power at a given receiver as is actually provided by the entire reflecting surface. [From Weik '89]

scattering loss

The part of the transmission (power) loss that results from scattering within a transmission medium or from roughness of a reflecting surface.

scavenge

To search, without authorization, through residual data to acquire sensitive information. [2382-pt.8]

scavenging

Searching through object residue to acquire data. [INFOSEC-99]
