Radiative transfer equation and diffusion theory for photon transport in biological tissue — Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A… … Wikipedia
Photon diffusion — refers to a situation where photons travel through a material with a high optical depth and very short mean free path. Their behavior is then dominated by scattering and the path of any given photon is effectively a random walk. A large ensemble… … Wikipedia
Bohm diffusion — is the diffusion of plasma across a magnetic field with a diffusion coefficient equal to:D {Bohm} = frac{1}{16},frac{k BT}{eB},where B is the magnetic field strength, T is the temperature, and e is the elementary charge.It was first observed in… … Wikipedia
