Patent ID: 8331194

Claim:
A system for underwater communication, said system comprising: an underwater communication platform capable of controllable movement, said underwater communication platform including a bubble field generator; a second communication platform capable of controllable movement; a bubble field extending between said underwater communication platform and said second communication platform with a forward end of said bubble field closest to said underwater communication platform and a trailing end of said bubble field closest to said second communication platform wherein said bubble field has a volume fraction of less than 0.03% gas; a power source; two terminals connected respectively to a positive and a negative portion of said power source, said terminals capable of being immersed in water and with said terminals capable of electrolysis of water forming bubbles at said terminals wherein a spacing between said terminals corresponds to a quarter wavelength of the acoustic signals transmitted within said bubble field; and two acoustic transceivers with one transceiver at said underwater platform and another transceiver at said second platform, each of said transceivers capable of transmitting and receiving acoustic signals within said bubble field.
