Waves Field Prediction of Different Polarization Mode in Mine Tunnels Based on Modern Information Technology

The propagation environment of electromagnetic waves in mine tunnels is confined areas. The mine tunnel is regard as wave-guide which contains kinds of un-beneficial medium, the field formulas of different polarization waves were presented based on Marcatili method, and field prediction of horizontal and vertical polarization waves were simulated. The results showed that propagation effect of vertical polarization waves was better than horizontal polarization wave in mine tunnels of breadth less than height, contrarily propagation attenuation of horizontal polarization waves were higher than vertical polarization waves in mine tunnels of height less than breadth, at the same time the field distribution would be influenced because of section dimension change.
