Abstract
U ovom radu opisani su mehanizmi propagacije elektromagnetskog vala s posebnim naglaskom na uvjete i čimbenike koji utječu na širenje valova u zatvorenim prostorima. Dan je pregled postojećih znanstvenih radova koji se bave propagacijom radio vala u podrumima i prostorima sličnim vinskim podrumima, kao što su tuneli. Praktični dio ovog rada sastoji se od mjerenja jakosti električnog polja u podrumu sličnih karakteristika vinskom podrumu, u prostorijama Fakulteta elektrotehnike, računarstva i informacijskih tehnologija u Osijeku te u vinskom podrumu u Kamencu. Mjerenja su provedena na različitim udaljenostima prijemne od odašiljačke antene, u uvjetima propagacije sa i bez direktne vidljivosti. Uz mjerenja odrađene su i simulacije u Matlab programskom okruženju, primjenom metode praćenja zrake. Simulacijama je napravljen proračun jakosti električnog polja u istim uvjetima u kojima je provedeno mjerenje (geometrija prostora, parametri odašiljačke i prijemne antene, položaji ispitivanih točaka), uz različit broj refleksija i difrakcija kako bi se utvrdio simulacijski model koji daje rezultate najbliže izmjerenima.
Abstract (english)
This paper describes the mechanisms of electromagnetic wave propagation, with a particular emphasis on the conditions and factors that affect wave propagation in enclosed spaces. An overview is provided of existing scientific studies that deal with radio wave propagation in basements and spaces similar to wine cellars, such as tunnels. The practical part of this work consists of measuring the electric field strength in a basement with characteristics similar to a wine cellar, in the rooms of the Faculty of Electrical Engineering, Computer Science, and Information Technology in Osijek, as well as in a wine cellar in Kamenac. Measurements were taken at various distances between the receiving and transmitting antennas, under conditions of propagation both with and without direct line of sight. In addition to the measurements, simulations were performed in the Matlab software environment using the ray-tracing method. The simulations calculated the electric field strength under the same conditions as the measurements (geometry of the space, parameters of the transmitting and receiving antennas, positions of the test points), with varying numbers of reflections and diffractions, to determine the simulation model that yields results closest to the measured values.
