Abstract
Ionosfera je zapravo plazma niske gustoće koja sadrži određeni broj nabijenih čestica, a međudjelovanje tih čestica može značajno promijeniti širenje elektromagnetskih valova. Ionosfera se sastoji od različitih slojeva koji su podložni raznim promjenama ovisno o dobu dana, mjeseca, godine te Sunčevim aktivnostima. Na širenje elektromagnetskog vala kroz ionosferu utječu slobodni elektroni, koji svojim titranjem upijaju energiju vala. Ionosfera je disperzijski medij čiji se indeks loma očituje kao promjena brzine širenja elektromagnetskog vala u područjima različite gustoće. Plazma u ionosferi emitira vlastite elektromagnetske valove koji mogu dodatno otežati komunikacije. Povećanjem frekvencije signala mogu se eliminirati mnogi negativni utjecaji ionosfere na komunikacije.
Abstract (english)
The ionosphere is actually low-density plasma, which contains a number of charged particles and the interaction of these particles can significantly change the propagation of electromagnetic waves. The ionosphere consists of different layers that are subject to various changes depending on the time of day, month, year and Solar activity. Vibrations of free electrons absorbe energy of the wave and affect the propagation of the electromagnetic wave through the ionosphere. The ionosphere is the dispersion medium, whose refractive index is manifested as a change in the velocity of propagation of electromagnetic waves in regions of different density. Ionospheric plasma emits its own electromagnetic waves that can further complicate communication. By increasing the frequency of the signal, many negative effects of the ionosphere on communications can be eliminated.
