Generalized optical theorem
In physics, the optical theorem is a general law of wave scattering theory, which relates the forward scattering amplitude to the total cross section of the scatterer. It is usually written in the form $${\displaystyle \sigma _{\mathrm {tot} }={\frac {4\pi }{k}}~\mathrm {Im} \,f(0),}$$where f(0) is the … See more The optical theorem was originally developed independently by Wolfgang Sellmeier and Lord Rayleigh in 1871. Lord Rayleigh recognized the forward scattering amplitude in terms of the index of refraction as See more • S-matrix See more The theorem can be derived rather directly from a treatment of a scalar wave. If a plane wave is incident along positive z axis on an object, then the wave scattering amplitude a great distance away from the scatterer is approximately given by See more Web(a) Show that the generalized optical theorem follows from the relation T ba= bjV j R a between the T matrix, the free state j R bi, the scattering state j a iand the interaction V, and the Lippmann-Schwinger equation. (b) Show that the optical theorem, ImT ii= 2ˇ X f (E i E f)jT fij; follows from the generalized optical theorem.
