Etude de la propagation des ondes électromagnétiques dans les tunnels courbes de section non droite pour des applications métro et ferroviaire

Autor: Masson, Emilie

This PhD research focuses on radio wave propagation modeling in curved tunnels with non- straight section for railway transportation. The solutions are developed in the form of a ≪ plu- gin ≫added to the core of an existing tool developed for wav
