A New 3D Ray-Tracing Acceleration Technique for the Analysis of Propagation and Radiation in Complex Enviroments

Abstract

A new 3D ray-tracing technique, based on the Angular Z-Buffer algorithm, [1] to speed-up reflection calculations is presented. The technique can be applied to the analysis of propagation in urban or indoor environments, or to the computation of radiation of antennas on-board complex structures amongst other applications. The technique is used in combination with the Uniform Theory of Diffraction (UTD) and shows a large reduction in CPU-time.
