High-frequency spectral asymptotics and homogenization for quasiperiodic operators
Elena Cherkaev, Bryn Davies, Sébastien Guenneau +2
We study the spectral asymptotics of elliptic operators with quasiperiodic coefficients by exploiting projections from higher-dimensional periodic functions. Using the framework of…
Fabry-Pérot quasinormal modes for topological edge states
Marc Martí-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…
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…
Platonic quasi-normal modes expansion
Benjamin Vial, Marc Martí Sabaté, Richard Wiltshaw +2
Elastic wave manipulation using large arrays of resonators is driving the need for advanced simulation and optimization methods. To address this we introduce and explore a robust f…
Dynamics of elastic lattices with sliding constraints
L. Cabras, D. Bigoni, A. Piccolroaz
This study investigates the impact of sliders -- constraints acting on elastic rods allowing for a transverse displacement jump while maintaining axial and rotational displacement…
Isospectral open cavities and gratings
Sebastiano Cominelli, Benjamin Vial, Sébastien Guenneau +1
Open cavities are often an essential component in the design of ultra-thin subwavelength metasurfaces and a typical requirement is that cavities have precise, often low frequency,…
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…
