Non-reciprocal elastic wave propagation in spatiotemporal periodic structures

New Journal of Physics, 2016
We study longitudinal and transverse wave propagation in beams with elastic properties that are periodically varying in space and time. Spatiotemporal modulation of the elastic properties breaks mechanical reciprocity and induces one-way propagation.
