High-speed acoustic communication through orbital angular momentum multiplexing

High-speed underwater communication is desired as we have more and more interactions with the ocean. Our everyday high-speed communication networks based on microwaves are not working underwater due to the strong absorption. Lights are not better due to the scattering. This is why acoustic waves (SONAR) is mainly used for underwater communications. But the low available frequency of sound waves limits the communication speed. Here, we use the multiplexing of orbital angular momentum to increase the information capacity of a single acoustic beam, and hence the communication speed.
