scattering coefficient

scattering coefficient

[′skad·ə·riŋ ‚kō·i‚fish·ənt]
(electromagnetism)
One of the elements of the scattering matrix of a waveguide junction; that is, a transmission or reflection coefficient of the junction.
(physics)
The fractional decrease in intensity of a beam of electromagnetic radiation or particles per unit distance traversed, which results from scattering rather than absorption. Also known as dissipation coefficient.

Using an analogous consideration for the scattering coefficient [[sigma].sub.s[lambda]]
Scattering coefficient of the brain tissue was modelled by [[mu]'.sub.s] = a[([lambda]/500nm).sup.-b], where[lambda] is the excitation or emission wavelength and a is a scaling factor which represents the reduced scattering coefficient at [lambda] = 500nm.
where [g.sup.m.sub.n,TM] and [g.sup.m.sub.n,TE] are the generalized functions of GLMT, an and bn are the scattering coefficient of Mie theory, and E and H are the magnetic and electric energy.
where [I.sub.[lambda]](x, [OMEGA]) is the spectral radiation intensity, [lambda] represents the wavelength, [[beta].sub.[lambda]] is the extinction coefficient, which is the sum of the absorption coefficient, [[kappa].sub.[lambda]], and [[sigma].sub.[lambda]] is the scattering coefficient. The ratio [omega] = [[sigma].sub.[lambda]]/[[beta].sub.[lambda]] is the scattering albedo coefficient which is inherent to each photocatalyst since it represents its photon absorption capacity.
Assuming that biological cells are approximate to homogeneous spherical particles, the scattering coefficient [Q.sub.sca] is computed from the rigorous Mie theory as given by [32]:
Thanks to this, the RBCs have a strong mismatch in refractive index and the scattering coefficient of the RBC is almost 1000 times larger than the scattering coefficient for any other blood particle.
1, the so called 'scattering coefficient' [gamma] at an arbitrary scattering direction ([[theta].sub.2], [[theta].sub.3]), which represents the scattered electric field at that direction normalized by the scattered electric field at the so--called 'specular direction', i.e.
The composite scattering characteristics can be evaluated by the scattering coefficient, as defined by
The absorption coefficient is denoted by [[mu].sub.a] (x), and the scattering coefficient is denoted by [[mu].sub.s] (x).
