摘要: Magnetic Induction (MI) communication technique has shown great potentials in complex and RF-challenging environments, such as underground underwater, due to its advantage over EM wave-based techniques penetrating lossy medium. However, the transmission distance of MI is limited since magnetic field attenuates very fast near field. To this end, paper proposes Metamaterial-enhanced (M$^2$I) mechanism, where a coil antenna enclosed by metamaterial shell that can enhance fields around transceivers. As result, M$^2$I system achieve tens meters range using pocket-sized antennas. In paper, an analytical channel model developed explore fundamentals aspects capacity, susceptibility various hostile environments. The theoretical validated through finite element simulation software, Comsol Multiphysics. Proof-of-concept experiments are also conducted validate feasibility M$^2$I.
