Webis above the plasma frequency, then refraction analogous to that which occurs with atmospheric refraction occurs, though it is much more pronounced because of the large changes in refractive index. In fact, provided the angle at which the wave enters the atmosphere is not too steep, the wave will be bent quite strongly as it enters ionosphere. Web1 dag geleden · According to [32], the propagation delay of an electromagnetic wave due to ionospheric refraction, can be expressed as follows (respectively for the delay induced by the phase refractive index Δ S i o n o, p (−) and for the delay induced by the group refractive index Δ S i o n o, g (+)): (14) Δ S i o n o = ± 40. 3 f 2 T E C where: f is the …

WebRocket ionosphere experiments give the relative delay of a pulsed signal as a function of rocket position. These data are used in an analysis to obtain the electron-density distribution with respect to height. This analysis, which takes into account the effects of the earth's magnetic field and the obliquity of the ray paths, is for the smooth, horizontally stratified …
