Labyrinthine acoustic metamaterials with space-coiling channels for low-frequency sound control
Anastasiia O. Krushynska, Federico Bosia, Nicola M. Pugno
We numerically analyze the performance of labyrinthine acoustic metamaterials with internal channels folded along a Wunderlich space-filling curve to control low-frequency sound in…
Polarized micro-Raman studies of femtosecond laser written stress-induced optical waveguides in diamond
B. Sotillo, A. Chiappini, V. Bharadwaj +7
Understanding the physical mechanisms of the refractive index modulation induced by femtosecond laser writing is crucial for tailoring the properties of the resulting optical waveg…
Observation of a Lamb band gap in a polymer waveguide with periodic cross-like cavities
M. Miniaci, M. Mazzotti, M. Radzieński +6
The quest for large and low frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration contr…
Emergence of the interplay between hierarchy and contact splitting in biological adhesion highlighted through a hierarchical shear lag model
Lucas Brely, Federico Bosia, Nicola M. Pugno
Contact unit size reduction is a widely studied mechanism as a means to improve adhesion in natural fibrillar systems, such as those observed in beetles or geckos. However, these a…
Mapping the local spatial charge in defective diamond by means of NV sensors - A "self-diagnostic" concept
J. Forneris, S. Ditalia Tchernij, P. Traina +11
Electrically-active defects have a significant impact on the performance of electronic devices based on wide band-gap materials such as diamond. This issue is ubiquitous in diamond…
A 2-D Model for friction of complex anisotropic surfaces
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
The friction force observed at macroscale is the result of interactions at various lower length scales that are difficult to model in a combined manner. For this reason, simplified…
Tuning friction with composite hierarchical surfaces
Gianluca Costagliola, Federico Bosia, Nicola M. Pugno
Macroscopic friction coefficients observed in experiments are the result of various types of complex multiscale interactions between sliding surfaces. Therefore, there are several…
Tunable spider-web inspired hybrid labyrinthine acoustic metamaterials for low-frequency sound control
A. O. Krushynska, F. Bosia, M. Miniaci +1
Attenuating low-frequency sound remains a challenge, despite many advances in this direction. Recently developed acoustic metamaterials enable efficient subwavelength wave manipula…
