Absorption in Hydro-Acoustic Networks

, 2013
Water covers over 70% of the globe, yet our ability to communicate in the underwater environment is limited. Radio and light communication through water suffer from such major issues that acoustic waves are the dominant form of cable-free underwater communication, but themselves suffer from low bandwidth and poor signal quality.

Active absorption of acoustic pulse in waveguide

Transactions of the Krylov State Research Centre, 2022
Object and purpose of research. A numerical model is taken as example to consider an active method of absorption for a short acoustic signal from reflecting boundary. Analysis is carried out on a model of virtual waveguide with rigid walls where the pulse with tonal content at one end and active absorption of the same at the other end is simulated. The
