| Popis: | The report presents an algorithmic approach to simulate electromagnetic fields in complex environments such as high density cities or areas with irregular topography. Many small reflecting and refracting objects, anisotropic media of wave propagation may produce complex maps of coverage by electromagnetic signals. Large amounts of these objects may result in large amounts of computations needed to perform an accurate simulation. A common approach of averaging those irregularities into virtual macro objects may not always be applicable when a detailed coverage map is needed, e.g. to study effects of an electromagnetic transmitter to other transmissions or to health of population in urbanized areas. A parallel simulation algorithm was developed to mitigate those issues. Assessment of the efficiency of the algorithm and its implementation also presented in the article shows high occupancy of parallel computing units and almost linear speedup of such simulation with an increase of the total processors involved. |
