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…
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…
On the Practicability of Ceramic-Tiled Walls for Sound Absorption by Tuning Cavities
Ozgur T. Tugut, Brahim Lemkalli, Qingxiang Ji +7
We present the practicality of structuring ceramic tiles for enhancing sound absorption on rigid walls. The cornerstone of our methodology is to structure walls with cavities so th…
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…
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,…
