The concept of metamaterial recently emerged as a new frontier scientific research, encompassing physics, materials science and engineering. In broad sense, indicates an engineered material with exotic properties not found in nature, obtained by appropriate architecture either at macro-scale or micro-/nano-scales. metamaterials can be tailored to open unforeseen opportunities for mechanical acoustic applications, demonstrated impressive increasing number studies. Building on this knowledge, theme issue aims gather cutting-edge theoretical, computational experimental studies elastic metamaterials, the purpose offering wide perspective recent achievements future challenges. This article is part ‘Current developments (Part 1)’.

An active elastic metasurface has more flexibility than a passively modulated metasurface, owing to the manipulation of phase gradient that can be realized without changing geometrical configuration. In this study, negative proportional feedback control system was employed provide positive stiffness for adaptive unit cells, with aim achieving modulation gradient. The relationship between gain and velocity flexural wave derived, transfer coefficients shifts through cells were resolved using matrix method. Finite element simulations propagations in conducted, they verified analytic solutions. Based on theoretical numerical work, we designed metasurfaces sub-wavelength thicknesses according generalized Snell’s law. These show abnormal functions transmitted waves, including refraction focusing, transforming guided waves at different operating frequencies by manipulating gain. Therefore, proposed great potential fields tunable design smart devices.

Abstract In this paper, we design a flexural metasurface capable of transforming plane or cylindrical waves into bottle shaped beam. The refractive index the is calculated by Generalized Snell’s Law and discretized 5 × 201 lattices, which finally realized resonant pillar-type unit cells. Simulation results demonstrate focusing effect metasurface, remains robust even in presence scatterer inside This work provides theoretical simulation foundation for application experiment beam wave control.
