The Symposium on Acoustic Metamaterials (SAM) 2026, organized by YRAM – Young Researchers in Acoustic Metamaterials, was a resounding success, bringing together researchers and industry experts to share groundbreaking work and foster collaboration.

Our doctoral candidates Alexander Kryuchkov, Juan Pablo Escudero, Nicolas Herrera, Line Mardini and Yves Pillot presented their research at the symposium:

• Alexander Kryuchkov presented “Utilizing Integrated Beam-Resonators to Characterize Manufacturing Variability in Selective Laser Sintered Metamaterials”, diving into methods for testing variability in beam builds produced by 3D printers.
• Juan Pablo Escudero delivered a talk titled “Building an Absorber Using Inclined Wiremesh Gratings”, exploring how omnidirectional absorption can be achieved through the reciprocity of the incident wave field and the strategic positioning of wiremesh gratings.
• Nicolas Herrera sparked a lively discussion with his talk on “Sonic Crystal Noise Barrier Design and Validation”, challenging conventional approaches to noise barriers.
• Line Mardini presented “WFEM-based assessment of the robustness of finite metamaterial vibration isolation under varying, realistic load cases”, demonstrating how partial and full bandgaps contribute to vibration attenuation in finite structures.
• Yves Pillot showcased his work on “Characterizing and Quantifying the Impact of Production Uncertainties on the Dynamic Response of a Series of Metamaterial Beams”, using model-order-reduction techniques to study variability in metamaterial beams.

A heartfelt thank you to YRAM for organizing SAM 2026 and creating such a dynamic platform for knowledge exchange.
