A magnetic induction based underwater communication
link is evaluated using an analytical model and a custom
FiniteDifference TimeDomain (FDTD) simulation tool. The
analytical model is based on the Sommerfeld integral, and a fullwave
simulation tool evaluates Maxwell’s equations using the FDTD
method in cylindrical coordinates. The analytical model and FDTD
simulation tool are then compared and used to predict the system
performance for various transmitter depths and optimum frequencies
of operation. To this end, the system bandwidth, signal to noise
ratio, and the magnitude of the induced voltage are used to estimate
the expected channel capacity. The models show that in seawater, a
relatively lowpower and small coils may be capable of obtaining a
throughput of 40 to 300 kbps, for the case where a transmitter is at
depths of 1 to 3 m and a receiver is at a height of 1 m.
