Numerical Modeling of the Effect of the Built Environment and Usages on Downlink EMF Exposure Induced by MU-MIMO 5G Antennas

Autor: Nicolas Noe, François Gaudaire

Publikováno v: 2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS).

In this paper we use numerical modeling to assess exposure to a MU-MIMO 5G antenna in different built environments. First, users are randomly distributed inside and outside buildings, and the channel between the antenna elements and the users is comp

Simulation of the indoor propagation of a 60GHz electromagnetic wave with a time-dependent radiosity algorithm

Autor: Kadi Bouatouch, Yannick Gabillet, François Gaudaire, Gilles Rougeron

Publikováno v: Computers & Graphics. 26:125-141

This paper describes a new time-dependent radiosity method (extended to specular reflection) that simulates the indoor propagation of a 60 GHz electromagnetic wave. The method requires two passes. During the first pass, the instantaneous radiosities

Reflection on curved surfaces in a 2.5D ray-tracing method for electromagnetic waves exposure prediction in urban areas

Autor: François Gaudaire, Nicolas Noe

Publikováno v: 2011 XXXth URSI General Assembly and Scientific Symposium.

Asymptotic methods are commonly used to predict exposure to electromagnetic waves in large environments such as urban areas. Specifically 2D beam-tracing is a very efficient solution in case of GIS 2.5D environments. Nevertheless taking into account
