Analytical Prediction of Buckling Limits in Isotropic Pentamode Lattices
M. Verbicaro, F. Braghin, R. V. Craster
Pentamode lattices are architected materials characterized by an elastic response dominated by a single deformation mode. The low stiffness of the other deformation modes, however,…
Weak scattering formulation for flexural waves in thin elastic plates with point-like resonators
Mario Lázaro, Marc Martí-Sabaté, Richard V. Craster +1
A theoretical study on the weak scattering formulation for flexural waves in thin elastic plates loaded by point-like resonators is reported. Our approach employs the Born approxim…
Wave propagation in beams with multiple resonators: conditions for weak scattering and the Born approximation
Mario Lázaro, Richard Wiltshaw, Richard V. Craster +1
This work reports the conditions under which weak scattering assumptions can be applied in a beam loaded by multiple resonators supporting both longitudinal and flexural waves. The…
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…
Localized Topological States beyond Fano Resonances via Counter-Propagating Wave Mode Conversion in Piezoelectric Microelectromechanical Devices
Jacopo M. De Ponti, Xuanyi Zhao, Luca Iorio +6
A variety of scientific fields like proteomics and spintronics have created a new demand for on-chip devices capable of sensing parameters localized within a few tens of micrometer…
Analytical approximations for multiple scattering in one-dimensional waveguides with small inclusions
Mario Lázaro, Richard Wiltshaw, Richard Vaughan Craster +1
We propose a new model to approximate the wave response of waveguides containing an arbitrary number of small inclusions. The theory is developed to consider any one-dimensional wa…
