Here, we demonstrate a magnetically tunable Mie resonance-based dielectric metamaterials. The magnetically tunable property is derived from the coupling of the Mie resonance of dielectric cube and ferromagnetic precession of ferrite cuboid. Both the simulated and experimental results indicate that the ...
Acoustic metamaterials (AMMs) are structures with acoustic properties enhanced or solely defined by their geometry, rather than by their intrinsic mechanical properties1. These are, typically, artificial structures of periodic, identical units with feature dimensions within the order of magnitude of the ...
We suggest and design new types of tunable metamaterials exhibiting either nonlinear magnetic or nonlinear electric response at microwave frequencies. By introducing a varactor diode as a nonlinear element within each resonator, we shift the frequency of either magnetic or electric resonance by changing ...
However, the exotic properties of metamaterials normally originate from the resonance mechanism of artificial atoms, thus inevitably limited in narrow band and hindering their practical applications. Here, we numerically design and experimentally verify a novel tunable dielectric metamaterial based on ...
Acoustic metamaterials have been designed to control the attenuation of acoustic waves, invisibility cloaking, and acoustic wavefront engineering, such as focusing via manipulating the acoustic impedance of metamaterials. The reviewed techniques are promising in extending the novel acoustics response into ...
The vast majority of multistable mechanical metamaterials realize tunable properties by coupling with other physical fields, such as thermal[25,48,52], magnetic[53,54], electrostatic[55], among others. For example, Meng et al.[56] combined a thermal-responsive active material (PLA) and a ...

(about a minute to reach a steady state). The proposed structure constitutes only a specific example of a new class of active elastic metamaterials that can be accessible by applying 3D printing techniques to photocurable polymers containing light-active units. Depending on the absorption spectrum ...
We present a systematic study on the optical and magneto-optical properties of Ni/SiO2/Au dimer lattices. By considering the excitation of orthogonal dipoles in the Ni and Au nanodisks, we analytically demonstrate that the magnetoplasmonic response of di
