Experimental Study of Road Guided Waves in a Snowy Mountain

Abstract

This paper presents the experimental results of radio propagation in a large groove guide. The groove guide examined here is a road surrounded by snow-packs of 5m in height in a snowy mountain. Experimental test was carried out on horizontal and vertical polarization characteristics in a frequency range from 150 MHz to 4.7 GHz. It is shown that the attenuation constants for both polarized waves decrease with increasing frequency below 1 GHz and increase slightly in higher frequency.
