  journal={2012 IEEE Industry Applications Society Annual Meeting},
This paper presents modeling results from National Institute for Occupational Safety and Health (NIOSH) research into through-the-earth (TTE) communications technology for underground coal mines. Research focuses on the factors controlling the propagation and coupling of radio signals between transmit and receive antennas separated by earth or coal. Most TTE sytems use single or multiturn loops of conductor for the transmit antenna. We compare the magnetic field distribution predicted from… CONTINUE READING
