Research output: Contribution to journalArticlepeer-review


A numerical method for solving the radiative transfer equation in a slab medium with isotropic scattering is presented. The method is based upon constructing the mth-degree interpolation polynomial to approximate the required solution using Legendre-Gauss-Lobatto collocation points. The differential and integral expressions which arise in the radiative transfer equation are converted into a system of linear algebraic equations which can be solved for the unknown coefficients. Numerical examples are included to demonstrate the validity and applicability of the method, and a comparison is made with existing results.
