Dispersion relations of generalized one-dimensional phononic crystals
Mario Lázaro, Richard Wiltshaw, Richard V. Craster +1
We present a comprehensive method for determining {both exact and approximate} dispersion {relations} for one-dimensional {resonant phononic} crystals, applicable to a wide range o…
Metamaterials and Fluid Flows
Francesco Avallone, Federico Bosia, Yi Chen +20
Understanding and controlling the dynamic interactions between fluid flows and solid materials and structures-a field known as fluid-structure interaction -is central not only to e…
Fabry-Pérot quasinormal modes for topological edge states
Marc MartÃ-Sabaté, Benjamin Vial, Richard Wiltshaw +2
Topological waveguides supporting quantum valley Hall interfacial states confine waves to interfaces and, due to topological protection, are resistant to backscattering even in the…
Surface Plasmon Polariton Excitation in Time-modulated Media
T. V. Raziman, Marie Touboul, Riccardo Sapienza +2
Surface plasmon polaritons (SPPs) are central to application areas such as sensing, energy harvesting, and nanoscale optics, and are typically excited via spatial structuring -- an…
Controlling the Propagation of Flexural Elastic Waves With Ceramic Metatiles
Brahim Lemkalli, Ozgur T. Tugut, Qingxiang Ji +5
In this work, we examine the application of phononic metamaterials for elastic impact noise insulation in tiled flooring, through the development of an innovative ceramic metatile…
Quasinormal modes of Floquet media slabs
Benjamin Vial, Richard V. Craster
Exploiting non-Hermitian wave-matter interactions in time-modulated media to enable the dynamic control of electromagnetic waves requires advanced theoretical tools. In this articl…
