Architected materials that control elastic wave propagation are essential in vibration
mitigation and sound attenuation. Phononic crystals and acoustic metamaterials use band …

The authors study the propagation of flexural waves in a locally resonant (LR) thin plate
made of a two-dimensional periodic array of spring–mass resonators attached on a thin …

We investigate theoretically the band structure of flexural waves propagating in an elastic
metamaterial thin plate. Kirchhoff-Love thin plate theory is considered. We study the …

We investigate the complex band structure and forced response of flexural waves
propagating in an elastic metamaterial thick plate. Mindlin-Reissner thick plate theory is …

The plane wave expansion method is extended to study the flexural wave propagation in
locally resonant beams with multiple periodic arrays of attached spring-mass resonators …

This paper presents a review study on sonic crystal, their development and present status.
