We are theoretical specialists with a keen interest in physical acoustics, elasticity, and vibrating engineered fluids or solids. Through mathematical modelling and numerical computation we explore novel acoustical and mechanical phenomena in structures on the nano-to-milli scale. Investigation the interaction in terms of acousto-electricity, elasto-plasmonics, etc. also belongs to our line of research [read more]
Visiting the “Organo” (1977) from Eusebio Sempere at Fundación Juan March here in Madrid.
Mechanical metamaterials have exotic properties that cannot be realized in conventional materials. In this Review, recently developed shape-morphing, topological and nonlinear metamaterials are discussed together with their functionalities and design principles. [read more]
The Meta-rod is the new generation of locally resonant sonic materials. The heavy beads are replaced by a rod that at resonance gives rise to an anisotropic mass-density permitting one to tailor the flow of elasticity at will. This man-made material produce even negative moments of inertia that block the evolution of torsional motions. [read more]
Vibrant times for Mechanical Metamaterials has been published as a small review article. Together with researchers from the group of Prof. Martin Wegener we discuss recent advances and outstanding challenges in this field. [read more]
Our earlier theoretical work on negative refraction just got real! Thanks to José Sánchez-Dehesa we demonstrated that the acoustic "fishnet" structure indeed is able to bend sound the "wrong" way! [read more]
What!? You are new to Acoustic Metamaterials? No problem! Thanks to Steve Cummer and Andrea Alu we put together a comprehensive review on this very line of research. Negative mass-density and bulk modulus, active structures and the emergence of acoustic Metasurfaces are something you can read about here![read more]
