GRID-Based Prediction of Electromagnetic Fields in Urban Environment

In this paper, a grid-based 3D ray tracing procedure is presented for the prediction of electromagnetic field in urban environment in the presence of multipaths, reflections and diffractions. In the procedure, electromagnetic field strength is obtained by all the contributions originated, evaluated by exploiting the ray tracing method in grid environment. The obtained results have shown the good performance of the grid environment for the prediction leading to reduction of one-order of magnitude of the computing time.
