We explore nonreciprocal vibration transmission in a nonlinear periodic waveguide.
Nonlinearity and asymmetry, the two necessary requirements for nonreciprocity, are both …

The influence of temperature on the unit cell wave attenuation of 1-D viscoelastic periodic
structures is important for the design of phononic structures and mechanical metamaterials …

Materials and devices subject to spatiotemporal modulation of their effective properties have
a demonstrated ability to support nonreciprocal transmission of waves. Most notably …

Vibration transmissibility in a material with spatiotemporal modulation can be changed by
just inverting the direction of transmission. This asymmetric feature of transmission can occur …

Reciprocity is an important property of wave propagation in materials. It ensures that waves
can propagate between two points in a material regardless of their direction of travel …

We highlight the contribution of phase to nonreciprocal vibration transmission in nonlinear
(passive) and spatiotemporally modulated (active) phononic lattices of finite length. We …
