Wireless communication is the prerequisite for the highly desired in-situ and real-time monitoring capability in underground environments, including oil reservoirs, groundwater aquifers, and volcanos, among others. However, existing wireless communication techniques do not work in such environments due to the harsh transmission medium with very high material absorption and the inaccessible nature of underground environment that requires extremely small device size. Although Magnetic Induction (MI) communication has been shown to be a promising technique in underground environments, the existing MI system utilizes very large coil antennas, which are not suitable for deployment in underground.
