Nonreciprocal scattering of elastic waves at time interfaces induced by spatiotemporal modulation
Yingrui Ye, Chunxia Liu, Alessandro Marzani +3
Spatiotemporally modulated elastic metamaterials have garnered increasing interest for their potential applications in nonreciprocal wave devices. Most existing studies, however, f…

Enhanced Sensitivity and Wave-Structure Interaction in Nonsingular Flat-Band Lattices with Compact Localized States
Emanuele Riva, Jacopo Marconi, Francesco Braghin
This paper investigates the dynamics of compact localized modes in one-dimensional flat-band elastic lattices. Flat dispersion arises from destructive interference between neighbor…

Creating compact localized modes for robust sound transport via singular flat band engineering
Riva Emanuele, Federico Bellinzoni, Francesco Braghin
We experimentally demonstrate the emergence of flat-band-induced compact-localized modes in acoustic Kagome lattices. Compact localized states populate singular dispersion bands ch…
