Abstract
Elektromagnetski valovi predstavljaju oblik elektromagnetskog polja, a sastoje se od promjenjivog električnog i magnetskog polja opisanih magnetskom indukcijom. Oba polja su po smjeru međusobno uvijek okomita i periodički se mijenjaju. Svaki elektromagnetski val posjeduje frekvenciju, kojom se iskazuje broj ponavljanja neke periodične pojave u jedinici vremena, kao i valnu duljinu koja je obrnuto proporcionalna frekvenciji. Rasprostiranje valova, odnosno propagacija jest funkcija frekvencije, što dovodi do toga da svako frekventno područje ima posebna svojstva. Visokofrekventno HF (engl. High Frequency) područje, koje se proteže od 3 MHz do 30 MHz, koristi se za radioveze na velikim udaljenostima. Ionosferski val se, zahvaljujući postojanju ionosfere i njene velike koncentracije elektrona, reflektira od iste i vraća na Zemlju, osiguravajući time veliki domet i mogućnost određivanja maksimalne iskoristive frekvencije MUF (engl. Maximum Usable Frequency). Navedeni pojmovi detaljno su opisani kroz poglavlja ovoga rada, u svrhu simuliranja utjecaja ionosfere na propagaciju elektromagnetskih valova na HF području.
Abstract (english)
Electromagnetic waves represent a form of electromagnetic field, consisting of a variable electric and magnetic field described by magnetic induction. Both fields are always in the vertical direction on each other, and periodic change. Each electromagnetic wave is owns a frequency, which shows the number of repetitions of a periodic occurrence in the unit of time, as well as the wavelenght, which is inversery proportional to the frequency. Wave propagation, is a function of frequency causing each frequency band to have specific performance. High frequency bandwidth, extanding from 3 MHz to 30 MHz, is used for global radioconnection. Wave, due to the existence of the ionosphere and its large electron concentrations is reflected from the same, returned to the Earth and ensure long range and possibility of determination MUF frequency. Mentioned concepts are detaily described through the chapters of this work, in a purpose of simulation of the impact of the ionosphere on the propagation of electromagnetic waves.
