Propagation of millimetric waves in rough sidewalls mining environment

This paper presents a model of the propagation of millimetric waves along lossy dielectric side walls of random roughness found in a mining environment. Two dimensional (2D) and three (3D) representations are obtained with a new analytical method, the segmental statistical method (SSM). It employs mathematical and geometric approaches linked to a magnetic vectors projection representation, with the use of the ray technique and the segmentation of the mining tunnel. Results are shown to be in accordance with those obtained using the classical Rayleigh roughness indicator. This new approach makes it possible to predict propagation performance in extreme conditions in a long mining corridor
