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

Neha ., Baljeet Kaur


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.

Keywords: Wave propagation, ray tracing, tri linear refractivity, ducting, anomalous propagation, PWE, HFSWR
