Abstract : The effect of particle motion or plasma 'wind' on waves propagated through the plasma is investigated. The solar wind is a plasma wind, and there appear to be high velocity winds in the ionosphere which may affect wave propagation in or through the ionosphere. The problem also arises in connection with the effect of massive moving plasmas on radio signals. To understand this situation, plane waves propagating in a uniformly flowing plasma are investigated. In this study, plane waves will be superimposed on a 'homogeneously flowing' plasma in which all the particles in the flow are executing motions similar to those of the single particles in first order orbit theory. Uniform flow is the special case of homogeneous flow in which electric balance exists so that all particles move with the same velocity. (Author)
