Physical Model of a Chiral Flexural Waveguide

We present a novel physical model of a gyrobeam, an active chiral structural element where flexural and rotational motions are coupled. In the literature, the gyrobeam is described as a mathematical object possessing a continuous distribution of stored angular momentum. In this paper, we show that gyrobeams can be realised by connecting gyroscopes to Euler-Bernoulli beams; in addition, we provide a physical interpretation of the gyricity parameter of a gyrobeam.
