AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A concept for acoustic metamaterials consisting of a cellular medium with fluid-filled cells is fabricated and studied experimentally. In such a system, the fluid and solid structure explicitly interact, and elastic wave propagation is coupled to both phas ...
We study the unique wave manipulation capabilities of Parity-Time symmetric pairs of metasurfaces operated at exceptional point conditions. We demonstrate theoretically and experimentally the relevance of these systems to induce wave phenomena typically ob ...
Soft materials are being adopted in robotics in order to facilitate biomedical applications and in order to achieve simpler and more capable robots. One route to simplification is to design the robot's body using 'smart materials' that carry the burden of ...
Internal degrees of freedom and periodic structure are critical requirements in the design of acoustic/elastic metamaterials since they can give rise to extraordinary properties like negative effective mass and stiffness. However, they are challenging to r ...
Periodic nanopatterning of metallic ferromagnets allows one to create devices with artificially tailored band structures for spin waves. We discuss our recent experiments performed on two-dimensional periodic lattices of nanoholes created in thin Ni80Fe20 ...
A transmission-line acoustic metamaterial is an engineered, periodic arrangement of relatively small unit-cells, the acoustic properties of which can be manipulated to achieve anomalous physical behaviours. These exotic properties open the door to practica ...
In recent years, an increasing number of pioneering studies have been carried out in the field of acoustic metamaterials, following the path of electromagnetic metamaterials. These artificial engineered materials are designed in such a way so as to achieve ...
Dynamic reconfiguration of antenna devices is becoming a prime need in emerging telecommunication and remote sensing systems operating in the portion of the electromagnetic (EM) spectrum spanning from millimeter-wave (MMW) to terahertz. Different technique ...
Acoustic metamaterials constitute a new class of structures that exhibit acoustic properties not readily available in nature. These properties can be a negative mass density, expressing the opposition of the acceleration of a particle to the application of ...
We explore the largely uncharted scattering properties of acoustic systems that are engineered to be invariant under a special kind of space-time symmetry, consisting in taking their mirror image and running time backwards. Known as Parity-Time symmetry, t ...
