We report on the tunability of the frequency-dependent permittivity of a metal-ferroelectric-metal (MFM) capacitor fabricated with P(VDF-TrFE), an organic ferroelectric material.

A mathematically defined 3D auxetic metamaterial with tunable mechanical and conduction properties
An auxetic metamaterial is a type of mechanical metamaterial that has a negative Poisson's ratio. Most auxetic metamaterials are truss-based or originate from Boolean operations of simple geometries.

Topological Insulator Metamaterials
Confinement of electromagnetic fields at the subwavelength scale via metamaterial paradigms is an established method to engineer light-matter interaction in most common material systems, from insulators to semiconductors, from metals to superconductors.

Tunable Broadband Transparency of Macroscopic Quantum Superconducting Metamaterials [PDF]
Narrow-band invisibility in an otherwise opaque medium has been achieved by electromagnetically induced transparency (EIT) in atomic systems. The quantum EIT behaviour can be classically mimicked by specially engineered metamaterials via carefully ...

Quantum master equation for coupling mechanism of metamaterial
In this paper, we present a full quantum description for coupling mechanism of the metamaterial. We start the derivation from quantum master equation to fit the spectrum of THz metamaterial. Therefore we can employ the quantum master equation to describe

Electrically tunable harmonics in time-modulated metasurfaces for wavefront engineering
Modulation of metasurfaces in time gives rise to several exotic space–time scattering phenomena by breaking the reciprocity constraint and generation of higher-order frequency harmonics. We introduce a new design paradigm for time-modulated metasurfaces,

Automatic design of mechanical metamaterial actuators [PDF]
Mechanical metamaterial actuators achieve pre-determined input–output operations exploiting architectural features encoded within a single 3D printed element, thus removing the need for assembling different structural components.

Transformation-Invariant Metamaterials [PDF]
The fundamental semiconductor concept of doping has recently been transplanted to photonics in the platform of epsilon-near-zero (ENZ) media. By doping nonmagnetic impurities, ENZ media can exhibit almost arbitrary magnetism. However, this original photonic doping approach results only in isotropic media and thus cannot achieve impedance matching for ...
