Autor: Marco Miniaci, Matteo Mazzotti, Maciej Radzieński, Pawel Kudela, Nesrine Kherraz, Federico Bosia, Nicola M. Pugno, Wieslaw Ostachowicz

Publikováno v: Frontiers in Materials, Vol 6 (2019)

Non-destructive testing and structural health monitoring (SHM) techniques using elastic guided waves are often limited by material inhomogeneity or geometrical irregularities of the tested parts. This is a severe restriction in many fields of enginee

Publikováno v: The Journal of the Acoustical Society of America. 139:2183-2183

Last years, a growing number of research has been devoted to the control of the behavior of Phononic crystals and Metamaterials through for instance tunability of the frequency position and/or width of a band gap. This can be achieved by using active
