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…

Analytical solutions for Bloch waves in resonant phononic crystals: Deep subwavelength energy splitting and mode steering between topologically protected interfacial and edge states
Richard Wiltshaw, Jacopo Maria De Ponti, Richard Vaughan Craster
We derive analytical solutions based on singular Green's functions, which enable efficient computations of scattering simulations or Floquet-Bloch dispersion relations for waves pr…
