Diatom frustules as naturally occurring resonant microarchitectures: revealing vibrational eigenmodes across pennate and centric species
Chiara Gazzola, Dame Fall, Stefano Stassi +3
Diatom frustules, the hierarchically structured, species-specific silica exoskeletons of diatom microalgae, are among Nature's most sophisticated examples of bottom-up self-assembl…

Longitudinal-flexural wave mode conversion via periodically undulated waveguides with constant and graded profiles
Vinicius F. Dal Poggetto, Fabio Nistri, Nicola M. Pugno +3
Wave mode conversion allows to transform energy from one propagating wave type to another at a boundary where a change in material properties or geometry occurs. Converting longitu…
