MATLAB and K-Wave Based Outdoor Ray Propagation Predictor Tool SNELLIX for Surface Wave Modelling

Abstract

This paper discusses the overview of ground wave propagation and addresses a particular class of propagation scenarios in the presence of surface terrain and atmospheric refractivity. Traditional methods used to predict the ground-wave field strength at low frequency and are not applicable for terrains with serious irregularities because of the analytical approximations. A virtual propagation MATLAB based predictor tool SNELLIX is developed for propagation of EM waves over non-flat terrain through homogeneous and an inhomogeneous atmosphere.
