We consider a gyro-elastic structured strip, formed from rods interconnecting periodically placed masses that are attached to gyroscopes. The presence of the gyroscopes makes the system non-reciprocal. Near bulk resonances of the strip, the medium is capable of supporting uni-directional Lamb waves when subjected to forcing [1]. We discuss the solution to this problem and demonstrate how these near-resonance effects can lead to designs of novel waveguides. Namely, we illustrate how we can create a network of structured strips that is capable of channelling the energy supplied by an external source towards any of its endpoints, which can be chosen arbitrarily and in advance.
