« Symposium on Acoustic Metamaterials (SAM) »

The fifth DENORMS workshop « Symposium on Acoustic Metamaterials” (SAM) took place from November 7 to 9, 2018 in Xàtiva (Spain), organised by YRAM (Young Researcher in Acoustic Metamaterials) and Universitat Politècnica de València.

This first Symposium on Acoustic Metamaterials was targeted to Early Career Investigators  (i.e. researcher whose career spun less than 8 years since the date of the PhD) and PhD candidates and aimed at sharing new advances and breakthroughs as well as fostering the community of young researchers in the field of acoustic metamaterials. The first SAM was organised around 6 different sessions comprising 20 min talks and 4 plenary lectures.

Topics covered by SAM are listed below but not restricted to:

• Acoustic/elastic metamaterials and phononic crystals
• Acoustic/elastic metasurfaces
• Non-reciprocal manipulation of acoustic/elastic waves
• Acoustic/elastic meta-devices based on transformation acoustics, parity-time symmetric acoustics, topological acoustics
• Novel physical concepts for harnessing acoustic/elastic waves
• New applications of metamaterial-based functional devices for acoustic sensing, cloaking, imaging, absorption, energy harvesting, etc.

Several social activities have been organised during the symposium.

The pictures of this SAM are available here.

You may read the book of abstracts, which is available here.
