Role of a fractal shape of the inclusions on acoustic attenuation in a nanocomposite
Haoming Luo, Yue Ren, Anthony Gravouil +4
Nanophononic materials are promising to control the transport of sound in the GHz range and heat in the THz range. Here we are interested in the influence of a dendritic shape of i…
Ballistic Heat Transport in Nanocomposite: the Role of the Shape and Interconnection of Nanoinclusions
Paul Desmarchelier, Alice Carré, Konstantinos Termentzidis +1
The effect on the vibrational and thermal properties of gradually interconnected nanoinclusions embedded in an amorphous silicon matrix is studied using MD simulations. The nanoinc…
A continuum model reproducing the multiple frequency crossovers in acoustic attenuation in glasses
Haoming Luo, Valentina M. Giordano, Anthony Gravouil +1
Structured metamaterials are at the core of extensive research, promising for acoustic and thermal engineering. Nevertheless, the computational cost required for correctly simulati…
