Simulating the Dispersion of the Energy Flux Density of the Electromagnetic Field Generated by Antennas for Mobile Communications – Raimondas Buckus, et al

Introduction: Electromagnetic radiation emitted by sources for cell telecommunications can be experimentally measured using a variety of software created for simulating the electromagnetic radiation. The simulation of the electromagnetic radiation of mobile telecommunications includes the analysis of a few different antennas emitting electromagnetic radiation, which is difficult in normal conditions, using mathematical models. The rapid growth of technologies in this sector is a significant factor in the growth of concentration too. A precise model helps with managing the electromagnetic fields of the source and helps in predicting impact factors of practical uses (e.g., impact on other structure or the area). Simulation is required for both the existing and intended objects and provides a possibility of foreseeable conditions under which electromagnetic radiation is of the necessary value but does not exceed the permitted limits.

Conclusions: The examination of the upcoming or available antenna or other powerful source of radio waves includes calculating the theoretical parameters of the density taking into account the qualities of the antenna and accepting surrounding terrain as an area with no significant unevenness. Similar places have most frequently installed antennas, and, although the obtained measurement results are satisfactory enough, in order to determine necessary safety requirements, the impact of land relief is unnecessarily downgraded. The wave propagated outwards the antenna is dispersed and, having reflected from terrain, is summed up with the previous one, thus creating a maximum. Uneven terrain changes the maximum position of this electromagnetic field, which needs further examination. Thus, if the simulated values are lower than the established standard, it is still advisable to check them experimentally.
