Propagation Estimation in Tenjin Area

Abstract

This paper is concerned with an application of ray tracing method (RTM) to electromagnetic wave propagation in Tenjin area, central part of Fukuoka city. Transmitter nad receiver are assumed to be in the same height as that of average human being. In this case we can neglect the effect of roof of buildings on propagation, since the wave, from a transmitter travels repeating reflections from the walls of buildings and a reflection from a road. Thus the propagation at the bottom of high-rise buildings is very similar to that in a tunnel. Numerical results are shown for ray examples and field distributions.
