摘要：Diffraction plays an important pat in V.H.F.radio wave propagation in mountainous terrains. The classical diffraction theory does not take into account the effect of polarisation. an experimental study of the effect of polarisation was made which indicates that horizontally polarised waved give greater diffracted fields than vertically polarised waved in the shadow region. The possible reasons for this were analysed.
