Superconducting metamaterials [PDF]
Physics Reports, 2018 Metamaterials (MMs), i.e. artificial media designed to achieve properties not available in natural materials, have been the focus of intense research during the last two decades. Many properties have been discovered and multiple designs have been devised that lead to multiple conceptual and practical applications. Superconducting MMs have the advantage

A Dual-Polarized Reconfigurable Reflectarray Antenna Based on a Symmetrically Rotated Sub-Array
IEEE Access, 2023 This paper proposes a novel method for designing a dual-polarized reconfigurable reflectarray antenna (RRA) based on a symmetrically rotated sub-array operating in a single-band.

Reports on Progress in Physics, 2023 Abstract Mechanical metamaterials, also known as architected materials, are rationally designed composites, aiming at elastic behaviors and effective mechanical properties beyond (‘meta’) those of their individual ingredients—qualitatively and/or quantitatively.

Science, 2009 Tunable Metamaterials The electromagnetic response of metamaterials gives rise to exciting phenomena such as cloaking, negative refraction, and perfect lensing. Their response, however, tends to depend strongly on resonant effects, thereby limiting the application bandwidth. Driscoll et al.

IEEE Access, 2020 Polarimetry is typically restricted to far-field characterization of a target using beam-like waves, which results in a 2 x 2 scattering matrix representation under two orthogonal in-plane polarization bases.

Metamaterials and imaging [PDF]
Nano Convergence, 2015 Resolution of the conventional lens is limited to half the wavelength of the light source by diffraction. In the conventional optical system, evanescent waves, which carry sub-diffraction spatial information, has exponentially decaying amplitude and therefore cannot reach to the image plane.

Optics Letters, 2022 We study the dispersion of electromagnetic waves in a spatially dispersive metamaterial with Lorentz-like dependence of principal permittivity tensor components on the respective components of the wave vector performing the analysis of isofrequency contours. The considered permittivity tensor describes a triple non-connected wire medium.

Molecular Plasmonics with Metamaterials [PDF]
Chemical Reviews, 2022 Molecular plasmonics, the area which deals with the interactions between surface plasmons and molecules, has received enormous interest in fundamental research and found numerous technological applications. Plasmonic metamaterials, which offer rich opportunities to control the light intensity, field polarization, and local density of electromagnetic ...

Magnetoelastic metamaterials [PDF]
2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011 We introduce the concept of magnetoelastic metamaterials with electromagnetic properties depending on elastic deformation. We predict a strong nonlinear and bistable response of such metamaterials caused by their structural reshaping in response to the applied electromagnetic field.
