Waves within a network of slowly time-modulated interfaces: time-dependent effective properties, reciprocity and high-order dispersion
Michaël Darche, Raphaël Assier, Sébastien Guenneau +2
We consider wave propagation through a 1D periodic network of slowly time-modulated interfaces. Each interface is modelled by time-dependent spring-mass jump conditions, where mass…
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…
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…
Scattering of transient waves by an interface with time-modulated jump conditions
Michaël Darche, Raphaël Assier, Sébastien Guenneau +2
Time modulation of the physical parameters offers interesting new possibilities for wave control. Examples include amplification of waves, harmonic generation and non-reciprocity,…
Propagation and non-reciprocity in time-modulated diffusion through the lens of high-order homogenization
Marie Touboul, Bruno Lombard, Raphaël Assier +2
The homogenization procedure developed here is conducted on a laminate with periodic space-time modulation on the fine scale: at leading order, this modulation creates convection i…
High-order homogenisation of the time-modulated wave equation: non-reciprocity for a single varying parameter
Marie Touboul, Bruno Lombard, Raphaël Assier +2
Laminated media with material properties modulated in space and time in the form of travelling waves have long been known to exhibit non-reciprocity. However, when using the method…
High-frequency homogenization for periodic dispersive media
Marie Touboul, Benjamin Vial, Raphaël Assier +2
High-frequency homogenization is used to study dispersive media, containing inclusions placed periodically, for which the properties of the material depend on the frequency (Lorent…
