Ray Tracing RF Field Prediction: An Unforgiving Validation
International Journal of Antennas and Propagation, 2015 The prediction of RF coverage in urban environments is now commonly considered a solved problem with tens of models proposed in the literature showing good performance against measurements. Among these, ray tracing is regarded as one of the most accurate

Implementation of Refined Ray Tracing inside a Space Module [PDF]
Journal of Systemics, Cybernetics and Informatics, 2012 Modern space modules are susceptible to EM radiation from both external and internal sources within the space module. Since the EM waves for various operations are frequently in the high-frequency domain, asymptotic raytheoretic methods are often the ...

60 GHz Indoor Propagation Studies for Wireless Communications Based on a Ray-Tracing Method
EURASIP Journal on Wireless Communications and Networking, 2007 This paper demonstrates a ray-tracing method for modeling indoor propagation channels at 60 GHz. A validation of the ray-tracing model with our in-house measurement is also presented. Based on the validated model, the multipath channel parameter such as
