“…At the same time, we may state that in the cases of the most powerful proton precipitations (such as on February 16, 1984 andSeptember 29, 1989) for which the effective height fell down to 50 (Remenets & Beloglazov, 1992;Remenets et al, 2020) and 45 km , one may expect similar qualitative results. But they should be quantitatively weaker, may be significantly, due to the absence of bremsstrahlung X-rays and the corresponding sporadic D s E -layer of the electric conductivity.…”

Previously the parameters of sporadic layer of electric conductivity caused by ultraenergetic relativistic electron (URE) precipitations were determined by us due to indirect electromagnetic method. Then we determined the southern boundaries of these precipitations in the frames of the following supposition: the effect of a normal wave reflection and its conversion into other normal waves on the boundary between disturbed and undisturbed parts of a radio path might have been ignored. Now we show by accurate simulation that it was true for strong and moderate URE precipitations. For the powerful disturbances of the same nature (16 events for 11 years) the effect is significant. In order to obtain these results, we had to change a traditional statement of problem about a normal wave conversion in the terrestrial waveguide and to solve numerically this new problem with an abrupt change of inhomogeneous properties on a transverse surface of the waveguide. We did not divide a near‐Earth waveguide at two artificial altitude parts: with vacuum and with inhomogeneous conducting medium along the transverse coordinate. Formally the waveguide was considered by us as inhomogeneous from its top to its bottom.
