    Fast and Reliable Locating of Points with the Maximum Value of Total Electromagnetic Fild Using a Modern Experimental Method for Radio Coverage in Urban Environment
    (Hindawi, 2014) Medjedovic, Petar S.; Suka, Darko S.
    This research has been performed within the project “prediction, measurement, and analysis of composite electromagnetic field of artificial radiation sources,” funded by theMinistry of Science and Technology of the Republic of Srpska, Bosnia and Herzegovina. The ultimate goal of the project is the installation of a monitoring network for continuous measurement and recording of nonionizing electromagnetic (EM) radiation levels in the wider area of Banja Luka city centre covering about 10 km2. For this reason it was necessary tomake an optimal choice from a dozen ofmeasurement points with themaximumvalue levels of total EM field. It was a difficult task, because in this case, with the resolution of 5m× 5m, approximately 400,000 points should be examined. Therefore, the pedestrian zones, areas, and routes with significantly smaller surfaces but with the largest flow of people have been examined, so the time required for their mapping with values of total EM field has been reduced to a more realistic framework. In this paper, in the volume allowed by the defined criteria, a fast and reliable experimental method has been described, which has been examined at one of the studied areas in the named project, with surface of 0.008 km2.

    Prediction and measurement of electromagnetic radiation at Krajina Square in the city of Banja Luka
    (2013) Medjedovic, Petar S.; Suka, Darko S.
    This work is only a small part of the research carried out in the project: "Prediction, measurement and analysis of composite electromagnetic (EM) field of artificial radiation sources", funded by the Ministry of Science and Technology of the Republic of Srpska. The main objective of the project is to locate the representative measuring points for future monitoring network for continuous measurements and recordings of maximum levels of EM non-ionizing radiation, in the spreading center of Banja Luka area of about 10km². Regarding that, previously was conducted verification with a software package used for a smaller area, by comparing the predicted and measured values of electromagnetic fields strength. For this purpose the pedestrian zones were treated, which are the surfaces and routes with the largest population flow. This paper gives a brief description of the research of EM radiation levels on the surface of 0.008km² in the frequency range from 50MHz to 3GHz.
