Second edition of the « Symposium on Acoustic Metamaterials » (SAM)
The second edition of the « Symposium on Acoustic Metamaterials” (SAM) took place from 9th to 11th October 2019 in Ischia (Italy) and was organised by YRAM (Young Researchers in Acoustic Metamaterials), COST Action DENORMS CA 15125 and the University of Salerno.
This second Symposium on Acoustic Metamaterials was targeted to PhD candidates, Early Career Investigators (i.e. researcher whose career spun less than 8 years since the date of the PhD) and aimed at sharing new advances and breakthroughs as well as fostering the community of young researchers in the field of acoustic metamaterials. The second SAM was organised around 6 different sessions comprising 20 min talks and plenary lectures.
More information can be found on the SAM website.
