Radio coverage prediction method in urban microcellular environment using electromagnetic techniques

A simulation method for the calculation of the radio propagation in urban area, sites is presented, based on analytical electromagnetic techniques. First of all we summarize the basic theory of physical optics (PO) and physical theory of diffraction (PTD) for the definition of first and second order reflected and diffracted fields in the far field area. We are also presenting formulas that calculate either numerically or analytically the near scattered electric field, because in a typical urban environment the scattered near field from walls occupies a large percentage of the area. Near field simulation results which are either in the form of potential coefficients or electric field vector appear for various data, inputs, resulting in a more accurate calculation of the electric field near the scattered surfaces
