The 5^th edition of the "Symposium on Acoustic Metamaterials" (SAM) will be held in Leuven, Belgium, from April 15^th to 18^th, 2026.

This Symposium on Acoustic Metamaterials is mainly dedicated to Ph.D. students and Early Career Investigators (i.e. researchers whose career spans less than 8 years since the date of the PhD) and aims at sharing new advances and breakthroughs in the field of acoustic metamaterials as well as fostering the community of young researchers. The 5^th SAM will be organised around six different sessions comprising 20-minute talks and plenary lectures.

Among others, addressed topics will be related to:

• Acoustic/elastic metamaterials and phononic crystals,
• Acoustic/elastic metasurfaces,
• Non-reciprocity, parity-time symmetry and temporal modulation for the manipulation of acoustic/elastic waves,
• Non-linear, non-Hermitian and topological acoustic/elastic systems,
• New applications of metamaterial-based functional devices for acoustic sensing, cloaking, imaging, absorption, insulation, energy harvesting.

Participation fees

For presenters/attendees at the Symposium: 275.00€.

The fee covers lunches on the 3 days of the symposium, coffee breaks in the morning and afternoon, and the social events from 15^th April 2026 to 17^th April 2026.

About the previous editions of SAM

The 1^st SAM was held in Xàtiva (Spain) from 7th to 9th November 2018, and was co-organized by YRAM, the Universitat Politècnica de València (UPV) and COST Action DENORMS (CA 15225). It was the first YRAM action to foster the community of young researchers in the field of acoustic and elastic metamaterials. It brought together 70 people, mainly ECIs. The scientific concert, open to all Xàtiva inhabitants — especially children — was a great success, and the concert hall was fully booked.

The 2^nd SAM was held in Ischia (Italy) from 9th to 11th October 2019, and was co-organized by YRAM, the University of Salerno, and COST Action DENORMS. It brought together around 70 participants from all over the world, many of whom were ECIs. A scientific popularization event on Acoustics Through Movies was held. The scientific event, open to all inhabitants of Ischia, was a great success, with over a hundred participants.

The 3^rd SAM was held in Nîmes (France) from 19th to 22nd October 2022, and was organized by YRAM. Not less than 75 participants from around the world attended the event, many of them ECIs. A scientific popularization exhibition on Acoustic Metamaterials through Comic Books was presented at the Centre Carré d’Art of Nîmes. The exhibition was open to the public for 1.5 months, and many schools participated in guided tours conducted by YRAM members during the week of the event. It was a great success, attracting more than a thousand visitors.

The 4^th SAM took place in Aegina (Greece) from 15th to 18th May 2024, and was organized by YRAM. It gathered over 50 participants from various countries. The event featured several internationally recognized plenary speakers, providing attendees with informal opportunities to engage with leading experts in the field. Alongside a rich scientific program, the island setting proved to be a perfect place for networking, fostering a relaxed and inspiring atmosphere. Participants also enjoyed cultural excursions, including a visit to the ancient Greek temple of Aphaia.
