✦ Synopsis

This paper presents a new 3-D ray-tracing technique based on image theory. The proposed method can be applied to urban microcellular en¨ironments with arbitrary building layouts and heights. A new hybrid method combining the uniform geometrical theory of diffraction (

) UTD with the near-field ray calculation method is also proposed in order to determine the diffraction loss due to propagation o¨er buildings.

Prediction results are in good agreement with measurements.
