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…

Non-Local Elastic Lattices with -Symmetry and Time Modulation: From Perfect Trapping to the Wave Boomerang Effect
Emanuele Riva
Wave motion is fundamentally constrained by the dispersion properties of the medium, often making it challenging -- or even impossible -- to guide wave packets along desired trajec…

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…
