1. A device comprising a plurality of waveguides disposed at arbitrary angles with respect to one another and phononic communication, wherein the communication takes place at a junction of the waveguides, wherein the device is configured such that a spectrum of acousto-elastic waves enters through one arm and is divided at the junction into different frequency bands, each of which is directed into different arms.
