Bound states in the continuum in circular clusters of scatterers
American Physical Society (2023-02-21)In this work, we study the localization of flexural waves in highly symmetric clusters of scatterers. It is shown that when the scatterers are placed regularly in the perimeter of a circumference the quality factor of the ... -
Broadband Asymmetric Propagation in Pillared Meta-Plates
MDPI (2020)The asymmetric propagation of mechanical energy across interfaces is a challenging problem with a wide range of applications. In this work, we present a novel structure presenting the asymmetric propagation of elastic waves ...

Coupling Helmholtz resonators for sound manipulation
IEEE (2021-09-20)In this work, we discuss the interaction between Helmholtz resonators, using the finite element method. We show that the coupling between two spheres gives rise to two resonant modes at low frequencies. One is symmetric ...

Generalized elastodynamic model for nanophotonics
American Physical Society (2020)A self-consistent theory for the classical description of the interaction of light and matter at the nanoscale is presented, which takes into account spatial dispersion. Up to now, the Maxwell equations in nanostructure ...

Gradient index phononic crystals and metamaterials
De Gruyter (2019)Phononic crystals and acoustic metamaterials are periodic structures whose effective properties can be tailored at will to achieve extreme control on wave propagation. Their refractive index is obtained from the ...

Intelligent on-demand design of phononic metamaterials
De Gruyter (2022-01-04)With the growing interest in the field of artificial materials, more advanced and sophisticated functionalities are required from phononic crystals and acoustic metamaterials. This implies a high computational effort and ...

Observation of two-dimensional acoustic bound states in the continuum
Springer Nature (2024-04-09)The design of devices based on acoustic or optical fields requires the fabrication of cavities and structures capable of efficiently trapping these waves. A special type of cavity can be designed to support resonances with ...

Robustness of conventional and topologically protected edge states in phononic crystal plates
American Physical Society (2018)Many efforts have been devoted to studying the robustness of topologically protected edge states in acoustics; however, the robustness of conventional edge states is rarely reported. In this work we theoretically ...

Single and coupled Helmholtz resonators for low frequency sound manipulation
American Institute of Physics (2022-08-12)In this work, we use the finite element method to study the acoustic properties of single and coupled Helmholtz resonators (HRs). Each HR consists of a sphere drilled with one or several small openings. For a single HR, ...

Topological States in Twisted Pillared Phononic Plates
Elsevier (2020-09-20)In recent years, the advances in topological insulator in the fields of condensed matter have been extended to classical wave systems such as acoustic and elastic waves. However, the quantitative robustness study of ...

Topological vortex mode for flexural waves in pillared plates
Elsevier (2023)Localized topological modes with high robustness to various perturbations are receiving increasing attention. Recently, zero-order topological vortex modes have been designed in phononic structures, in analogy with ...
