Parallel Ray Tracing Algorithm for Numerical Analysis in Radiative Media Physics

, 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.

A Study on Physical Layer Security Through Ray Tracing Simulations

2022 16th European Conference on Antennas and Propagation (EuCAP), 2022
Due to its broadcast nature, the wireless channel cannot be really private, i.e. restricted to the intended users only. Rather, it can always be available also to some unauthorized outsider, and, thus, security in wireless communications is crucial.

Comparison of ray traced based models with Physical Optic model

2016 URSI International Symposium on Electromagnetic Theory (EMTS), 2016
Electromagnetic wave propagation in free space is an excessively simplified situation. Hence, the vital question is how an electromagnetic wave propagates in ambient including obstructions like mountains, trees, hills or buildings. These obstructions reflect, diffract and scatter the electromagnetic waves.

Implementation and Hybridization of Physical Optics, Born Approximation, and Ray Tracing

2018 International Workshop on Computing, Electromagnetics, and Machine Intelligence (CEMi), 2018
The frequency domain simulation of the scattering behavior of electrically large homogeneous dielectric objects, especially in the context of inverse scattering, is a challenging task well suited for the application of the method of physical optics. In this paper we propose the hybridization of the method of physical optics, the Born-approximation and ...

Physical statistical modelling of the land mobile satellite channel based on ray tracing

IEE Proceedings - Microwaves, Antennas and Propagation, 1999
The paper presents a model of the land mobile satellite channel, predicting the statistical fade distribution in a given urban or suburban area described by objective data. The channel modelling is based on a conditional Rician distribution, whose parameters are related to physical parameters such as building height, street width, azimuth and elevation
