Abstract Tunable metasurfaces show promising applications in modulating flexural waves, but existing research lacks effective modulation of multidirectional flexural waves. In this paper, a tunable radial metasurface is proposed, which is able to manipulate the flexural waves to achieve various functions, especially the control of the single-focus and multi-focus focusing positions inside the metasurface. The tunable radial metasurface consists of arc sub-units, and the height of the slider in the arc sub-units can be adjusted to obtain a phase shift covering a range of 2 π with a high transmi

Existing tunable optical metasurfaces based on the electro-optic effect are either complex in structure or have a limited phase modulation range. In this paper, a simple rectangular metasurface structure based on a Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) crystal with high electro-optic coefficient of 120 pm/V was designed to demonstrate its electrically tunable performance in the optical communication band through simulations. By optimizing the structure parameters, a tunable metasurface was generated that can induce a complete 2π phase shift for beam deflection while maintaining relatively uniform t

In this paper, inspired by origami structures, we offer a very simple tuning method to overcome the limitations of general elastic metasurfaces, where only a certain functionality at a certain frequency range can be achieved, by designing a reflective metasurface based on foldable/deployable zig-zag structures. By utilizing peg/screw connections, the folding angles of the zig-zag structures can be easily tuned while also being fixable. By tuning the folding angle, the subunit of the zig-zag metasurface can cover a 2π phase shift span and the phase shift can be tuned continuously, and almost li

Moreover, the functions of acoustic beam steering and focusing by the designed metasurface at three arbitrarily chosen frequencies are verified in simulation. Th

Metasurfaces with both multifunctionality and tunability hold great application potential in next-generation optical devices.

It is shown that the metasurface possesses three functions at the operating wavelength of 532 nm. The switching of functions can be implemented by changing the period Px of the metasurface, induced by stretching the PDMS substrate along the x-direction.

The emergence of metamaterials has presented an unprecedented platform to control the fundamental properties of light at the nanoscale.

A key active control mechanism of optical properties involves the use of mechanical deformation, aided by deformable polymeric substrates. The use of deformable polymeric

In a 2D array, the resonance from the individual nanoparticles interferes with the Rayleigh anomalies (RAs) of the periodic structure to produce a collective surface lattice resonance (SLR).
