  The demand for high data rates is rapidly increasing as the interest in
Magnetic Induction (MI) communication-based underwater applications grow.
However, the data rate in MI is limited by the use of low operational frequency
in generating a quasi-static magnetic field. In this paper, we propose the use
of full-duplex (FD) MI communication to efficiently utilize the available
bandwidth and instantly double the data rate. We propose a two-dimensional
transceiver architecture to achieve full-duplex communication by exploiting the
directional nature of magnetic fields. We further evaluate the proposed
end-to-end FD MI communication against self-interference (SI), its impact on
communication distance, and robustness in view of orientation sensitivity.
Finally, we conclude by discussing typical challenges in the realization of FD
MI communication and highlight a few potential future research directions.
