A proposal to improve ray launching techniques
(IEEE Antennas and Wireless Propagation Letters, 2018-11-23)
In this letter, we demonstrate the implementation of an algorithm to model three-dimensional ray launching. A fixed-size reception sphere and cylinder are used in conjunction with numerical methods to simulate multipath ...
Analysis of heuristic uniform theory of diffraction coefficients for electromagnetic scattering prediction
(International Journal of Antennas and Propagation, 2018-03-07)
We discuss three sets of heuristic coefficients used in uniform theory of diffraction (UTD) to characterize the electromagnetic scattering in realistic urban scenarios and canonical examples of diffraction by lossy conducting ...
