Properties of random media are frequently investigated by studying their interactions with stochastic electromagnetic fields. However, a stochastic beam does not necessarily retain its beamlike form on scattering, and the theory of stochastic electromagnetic fields that are not beamlike is rather complicated. In this paper a necessary and sufficient condition is derived for a beam to retain its beamlike form after it is scattered on a stochastic medium. We illustrate the result by an example.
