Scattering — is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more localized non uniformities in the medium through which they pass. In… … Wikipedia
Scattering parameters — or S parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering describing the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small… … Wikipedia
Scattering Matrix Method — In computational electromagnetics, Scattering Matrix Method (SMM) is a numerical method used to solve the Maxwells equations.PrinciplesSMM uses cylinders to model dielectric/metal objects in the domain. The total field/scattered field (TF/SF)… … Wikipedia
Low-energy ion scattering — LEIS redirects here; for the Hawaiian garland see Lei (Hawaii). Low energy ion scattering spectroscopy (LEIS), sometimes referred to simply as ion scattering spectroscopy (ISS), is a surface sensitive analytical technique used to characterize the … Wikipedia
Thomson scattering — In physics, Thomson scattering is the scattering of electromagnetic radiation by acharged particle. The electric and magnetic components of theincident wave accelerate the particle. As it accelerates, it in turn emits radiation and thus, the wave … Wikipedia
Anomalous X-ray scattering — AXRS or XRAS is a technique within X ray diffraction that makes use of the anomalous dispersion that occurs when a wavelength is selected that is in the vicinity of an absorption edge of one of the constituent elements of the sample.Atomic… … Wikipedia
Multiangle light scattering — (MALS) is a technique for determining, independently, the absolute molar mass and the average size of particles in solution, by detecting how they scatter light. Collimated light from a laser source is most often used, in which case the technique … Wikipedia
Small-angle neutron scattering — (SANS) is a laboratory technique, similar to the often complementary techniques of small angle X ray scattering (SAXS) and light scattering. These are particularly useful because of the dramatic increase in forward scattering that occurs at phase … Wikipedia
X-ray Raman scattering — (XRS) is non resonant inelastic scattering of x rays from core electrons. It is analogous to Raman scattering, which is a largely used tool in optical spectroscopy, with the difference being that the wavelengths of theexciting photons fall in the … Wikipedia
Bhabha scattering — Notice that there is a relative sign difference between the two diagrams.quare of matrix elementTo calculate the unpolarized cross section, one must average over the spins of the incoming particles ( s e and s e+ possible values) and sum over the … Wikipedia
surface analysis — ▪ chemistry Introduction in analytical chemistry (chemistry), the study of that part of a solid that is in contact with a gas or a vacuum. When two phases of matter are in contact, they form an interface. The term surface is usually… … Universalium
