Surface wave non-reciprocity via time-modulated metamaterials

Kavli Affiliate: Chiara Daraio | First 5 Authors: Antonio Palermo, Paolo Celli, Behrooz Yousefzadeh, Chiara Daraio, Alessandro Marzani | Summary: We investigate how Rayleigh waves interact with modulated resonators located on the free surface of a semi-infinite elastic medium. We begin by studying the dynamics of a single resonator with time-modulated stiffness. In particular, we […]
