Note 1: Aperture-to-medium coupling loss is related to the ratio of the scatter angle to the antenna beamwidth. Note 2: The "very large antennas" are referred to in wavelengths; thus, this loss can apply to line-of-sight systems also.

Visulization of flux through differential area and solid angle. As always n ^ {\displaystyle \mathbf {\hat {n}} \,\!} is the unit normal to the incident surface A, d A = n ^ d A {\displaystyle \mathrm {d} \mathbf {A} =\mathbf {\hat {n}} \mathrm {d} A\,\!} , and e ^ ∠ {\displaystyle \mathbf {\hat {e}} _{\angle }\,\!} is a unit vector in the ...
The formula describes both the Thomson scattering of low energy photons (e.g. visible light) and the Compton scattering of high energy photons (e.g. x-rays and gamma-rays), showing that the total cross section and expected deflection angle decrease with increasing photon energy.
The differential angular range of the scattered particle at angle θ is the solid angle element dΩ = sin θ dθ dφ. The differential cross section is the quotient of these quantities, dσ / dΩ . It is a function of the scattering angle (and therefore also the impact parameter), plus other observables such as the momentum of the ...
X-ray atomic form factors of oxygen (blue), chlorine (green), Cl − (magenta), and K + (red); smaller charge distributions have a wider form factor.. In physics, the atomic form factor, or atomic scattering factor, is a measure of the scattering amplitude of a wave by an isolated atom.
Multi-Angle light scattering describes a technique for measuring the light scattered by a sample into a plurality of angles. It is used for determining both the absolute molar mass and the average size of molecules in solution , by detecting how they scatter light .
