Abstract : The theory of propagation of electromagnetic waves in a statistically inhomogeneous medium is examined for the models of the medium: (1) the discrete scatterer model, (2) the perturbed continuum model. The theory is based on the assumption that the lifetime of a configuration of the system is long compared with the period of the primary time harmonic wave. It is generally assumed also that averages of the field obtained by the ensemble method are equivalent to long time averages over the time series that the actual field constitutes. These assumptions are examined and their implications are pointed out. It is shown that there is a complete correspondence between the methodology used for the discrete scatterer model and the perturbed continuum model.
