Physics based ray-tracing propagation model for suburban areas

open access: closedIEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004
In this paper a hybrid model has been developed based on a physics-based model for the forest and a ray-tracing algorithm. Using the physical model of the forest, effective dielectric constant is found and applied to the raytracing algorithm. This 3-D modeler can consider objects with different shape and position, and therefore the simulator can be ...

Polarization ray tracing in anisotropic optically active media II Theory and physics

open access: closedJournal of the Optical Society of America A, 1993
Refraction, reflection, and amplitude relations are derived that apply to polarization ray tracing in anisotropic, optically active media such as quartz. The constitutive relations for quartz are discussed. The refractive indices and polarization states associated with the two modes of propagation are derived as a function of wave direction.

Parallel Ray Tracing Algorithm for Numerical Analysis in Radiative Media Physics

open access: closed, 2018
An original algorithm was developed for ray tracing across unstructured 3D grid. The resulting set of rays provides the base for the grid-characteristic computation of radiative energy transfer in the high temperature plasma simulations using MPI parallel technique and grid decomposition.
