Under the conditions in which we are most interested here, i.e. long-distance radio propagation, many encounters with the ionosphere will have occurred. Although none of these will be a passage right through the ionosphere, most being a double passage at an oblique an

Angular Spread of Waves,re now considering is a little different from that considered in chapter 7 where the rough ionospheric and earth reflections gave rise to the day-to-day wandering of the rays. We are now concerned with the “instantaneous” picture i.e. the actual spread of power at some particular time.
