Opal: An open source ray-tracing propagation simulator …
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8598032/
Propagation simulation by ray launching has usually been used for EM characterization of static environments, where the transmitter is kept fixed at a few positions , mainly because of a lack of tools for proper representation of dynamical 3D environments and low performance of the tracing process. On the contrary, ray tracing engines such as OptiX have …
Modelling Ray Tracing Propagation Data Using Different …
https://ieeexplore.ieee.org/document/9135639
In this paper, we apply different machine learning methods for the prediction of path loss in urban environment for cellular communications with unmanned aerial vehicles (UAVs). We generate the training set using a ray tracing technique assuming a flying base station at different heights within the city of Tripolis, Greece. We produce prediction models for the path loss using three …

J. Ling, & J. Moore. Radio propagation measurements and prediction using three -dimensional ray tracing in urban Ray tracing for RF simulation Optical ray tracing simulates the propagation of visible light in complex 3D environments and also elegantly handles important effects such as direct line -of -sight,
StingRay: High-Performance RF Energy Propagation …
https://dsiac.org/articles/stingray-high-performance-rf-energy-propagation-modeling-in-complex-environments/
StingRay is explicitly designed to support high-performance, high-fidelity simulation and visualization of RF energy propagation in complex urban environments by exploiting modern multicore computer architectures, particularly Intel’s Xeon processor family. High-performance RF simulation is achieved with Intel’s Embree ray tracing kernels [1], and …

the ray-tracing result the effects of buildings in the estimation area are reflected strongly, as can be seen from the tendency for reception power to be higher along roads and at intersections in Fig. 3 (b). This ability of ray-tracing methods to estimate propagation characteristics in a unified way for various types of environment is extremely promising.
3 Radio Propagation Modeling - University of Colorado …
https://morse.colorado.edu/~tlen5510/text/classwebch3.html
The well-known two-ray model uses the fact that for most wireless propagation cases, two paths exist from transmitter to receiver: a direct path and a bounce off the ground. That model alone shows some important variations of the received signal with distance. Ray tracing models are extensively used in software propagation prediction packages, which justifies a closer look at …
