Abstract
A system for underwater communications through a region between a transmit antenna and a receive antenna using electromagnetic signals. When the system is in an inactive mode, the region is occupied by water. When the system is in an active mode, fluid having a reduced conductivity is introduced into the region to provide transmission of electromagnetic signals with a lower attenuation and thereby facilitate a higher data transfer rate for a given range of communication between the transmit antenna and the receive antenna.
