2n-Stream Radiative Transfer

  title={2n-Stream Radiative Transfer},
  author={William Arie van Wijngaarden and William Happer},
We use 2 n = 2 , 4 , 6 , . . . “streams” of axially symmetric radiation to solve the equation of transfer for a layered medium. This is a generalization of Schuster’s classic 2-stream model. As is well known, using only the first 2 n Legendre polynomials to describe the angular dependence of radiation reduces the equation of transfer to a first order differential equation in a space of 2 n dimensions. It is convenient to characterize the radiation as 2 n stream intensities I ( µ i ), propagating…
