Urban radio wave propagation: A 3-D path-integral wave analysis

Research output: Contribution to journalArticlepeer-review


Colleges, School and Institutes


A discussion concerning the need for threedimensional (3-D) urban radiowave propagation models is presented and followed by a review of previously published work on this topic using the asymptotic path-integral technique. The limitations and advantages of this technique are explained and it is applied to study diffraction by a small number of canonical geometries. The validity of this technique is verified by comparison with controlled laboratory measurements taken at millimetric wave frequencies. Finally, its ability to classify field components according to their distribution in space is employed in order to analyze the observed field strength distributions in the model environments.
