Abstract 

The prototype transmitter was placed on the floating platform for generating the inductive magnetic field, and the distance between the rotating magnet and the sea surface is 35 cm to 45 cm. The waterproof ferrite-rod coil was hung in the seawater as a receiving antenna at a depth of 10 m.

Instructions: 

An undersea MI communication experiment was conducted using the test system in a port in Sanya, China. The test site is about 100 m near the lands and 20 m near the ships. The seawater conductivity of the test site is measured to be 3.92 S/m.
