Abstract
Magnetic Induction (MI) communication technique may provide promising solution than EM wave-based communication technique for underwater and underground applications where behavior of RF environment is complex, challenging and channel conditions are not constant. The propagation medium is other than air in such applications. MI communication technique overcomes the dynamic channel, propagation loses and antenna size issues of EM wave-based technique. In spite of these benefits, MI communication range is limited due to very fast attenuation of magnetic field with distance. Metamaterial shells are used to reduce the losses and hence improving the communication range. In M2I communication, MI coil antennas are encased by a metamaterial shells, which amplifies the magnetic field around transceivers as a result, range. In this paper, two metamaterial shells are utilized i.e. Double layer Metamaterial-Improved magnetic induction (DM2I) communication but radius of antenna with metamaterial shells is same as in M2I. Comsol Multiphysics, a Finite Element method (FEM) software is used to design and simulation of the analytical channel. The results show that the efficiency is improved in DM2I as compared with M2I.
