A study of scattering characteristics using polygon meshed PO

The polygon meshes represented by several triangles are applied to implement the physical optics (PO) approximation method. The polygon meshes can now be easily generated by the intrinsic function of MATLAB. "Polygon Meshed PO" method was implemented and examined for modeling the scattering characteristics from 3D objects. Using Polygon Meshed PO, the calculation of the induced current and the scattered field can be systematically simplified by summing the contribution on each triangle. Furthermore, the parametric study and the analytical solutions including integral equation (IE) techniques were introduced in order to evaluate the performance of this method

Polar directional characteristics of the urban mobile propagation channel at 2.2 GHz

The initial analysis of the data obtained from an extensive measurement campaign in Tokyo and Yokohama metropolitan areas are presented. Measurements were performed in non-line-of-sight (nLoS) macrocell scenario for which both vertically and horizontally polarized antennas were employed for transmitting and receiving signals. We are specifically interested to investigate the principal propagation mechanisms in such environments. This was done by obtaining the angular spread of the received signals in azimuth and elevation which was achieved by rotating a vertically deployed linear array at the mobile-terminal (MT). The propagation mechanisms were analyzed in respect to the orientation of the street where MT is located
