Reflection of Electromagnetic Waves at Ionized Media with Variable Conductivity and Dielectric Constant

Using the electrical properties obtained by the higher atmosphere on account of the ionization caused by the ultra-violet radiation of the sun and the corpuscular rays sent out from it conclusions are drawn about the height where electromagnetic waves are reflected and the reflected amplitude. In this way results can be obtained in good agreement with the observations. The influence of hydrogen in the upper atmosphere is discussed. Finally the reflection time for a signal is calculated.
