WebWhen EM waves travel from air to water or water to air, there is a refraction loss due to the change in the medium. This loss can be calculated from the following formula: Refraction …
A few nations have built transmitters which use extremely low frequency (ELF) radio waves, which can penetrate seawater to reach submarines at operating depths, but these require huge antennas. Other techniques that have been used include sonar and blue lasers . See more Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors See more Sound travels far in water, and underwater loudspeakers and hydrophones can cover quite a gap. Apparently, both the American (SOSUS) and the Russian navies have placed sonic … See more Electromagnetic waves in the ELF and SLF frequency ranges (3–300 Hz) can penetrate seawater to depths of hundreds of meters, allowing signals to be sent to submarines at their … See more A recent technology developed by a team at MIT combines acoustic signals and radar to enable submerged submarines to communicate with airplanes.
