Active plasmonic devices and optical metamaterials [PDF]
, 2009 We studied active near-infrared metamaterials based on phase transition of vanadium oxide thin films, asymmetrically coupled split-ring resonators for narrowing resonance line-widths , field effect modulation of plasmon propagation and 3D single layer ...

Adaptive Multichannel Terahertz Communication by Space-Time Shared Aperture Metasurfaces
IEEE Access, 2020 We propose a technique for adaptive multichannel communication in the low-terahertz frequency regime through simultaneous and independent multifrequency multibeam scanning via a single time-modulated metasurface consisting of graphene micro-patch ...

Programmable Mechanical Metamaterials [PDF]
, 2014 We create mechanical metamaterials whose response to uniaxial compression can be programmed by lateral confinement, allowing monotonic, non-monotonic and hysteretic behavior.

Transformation-Invariant Metamaterials [PDF]
Physical Review Letters, 2019 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 ...

Beyond local effective material properties for metamaterials [PDF]
, 2017 To discuss the properties of metamaterials on physical grounds and to consider them in applications, effective material parameters are usually introduced and assigned to a given metamaterial. In most cases, only weak spatial dispersion is considered.

Physics-informed neural networks for inverse problems in nano-optics and metamaterials. [PDF]
Optics Express, 2019 In this paper, we employ the emerging paradigm of physics-informed neural networks (PINNs) for the solution of representative inverse scattering problems in photonic metamaterials and nano-optics technologies.
