INVARIANT IMBEDDING AND SCATTERING OF LIGHT IN A ONE=DIMENSIONAL MEDIUM WITH A MOVING BOUNDARY.

摘要

It is shown how the invariant-imbedding technique is used for the derivation of integral equations governing the reflection and the transmission coefficients of radiation in a one-dimensional medium with a moving boundary. When formulating the source function,account is taken by the relaxation of photon emission under the assumption that during an elementary act of scattering a photon remains in a state of absorption for a certain duration of temporal capture. The Schuster problem for a moving one-dimensional medium is exactly treated. When formulating the transfer equations,the influence of the Doppler effect caused by the macroscopic differential motions is considered as a principal agency of the change of frequency on scattering.
