WebThe effects of reflections on the radio channel are very important in propagation studies. We will start off by looking at the simplest case of a reflection from a smooth flat surface of infinite extent. This is one of those cases that does not really exist, but as long as the surface is large compared to the size of the Fresnel zone, it will ...
