Experimental demonstration of nonreciprocal propagation in a piezoelectric phononic crystal with spatio-temporal modulation of electrical conditions

Résumé

This work concerns the experimental study of the propagation of elastic waves in a piezoelectric phononic crystal made of several identical piezoelectric elements separated by thin electrodes. We analyze the effect of spatio-temporal modulation of electrical conditions on wave propagation. The experimental results show the presence of directional band gaps on the dispersion curves for certain modulation speeds.
