Magnetoelastic metamaterials [PDF]

open access: yes2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011
The study of advanced artificial electromagnetic materials, known as metamaterials, provides a link from material science to theoretical and applied electrodynamics, as well as to electrical engineering. Being initially intended mainly to achieve negative refraction, the concept of metamaterials quickly covered a much broader range of applications ...

Mechanical metamaterials

open access: yesReports 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.

Metamaterial superconductors [PDF]

open access: yesNanophotonics, 2015
Abstract Searching for natural materials exhibiting larger electron‐electron interactions constitutes a traditional approach to high‐temperature superconductivity research. Very recently, we pointed out that the newly developed field of electromagnetic metamaterials deals with the somewhat related task of ...

Topological Metamaterials

open access: yesChemical Reviews, 2023
One of the most significant breakthroughs in physics of the last decade has been the discovery that materials with non-trivial topological properties for electronic, electromagnetic, acoustic and mechanical responses can be designed and manufactured at our will through engineered metamaterials (MMs).

Advanced Processing of 3D Computational Microwave Polarimetry Using a Near-Field Frequency-Diverse Antenna

open access: yesIEEE 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.

Memory Metamaterials [PDF]

open access: yesScience, 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.

Microelectromechanical Maltese-cross metamaterial with tunable terahertz anisotropy [PDF]

open access: yes, 2012
Dichroic polarizers and waveplates exploiting anisotropic materials have vast applications in displays and numerous optical components, such as filters, beamsplitters and isolators. Artificial anisotropic media were recently suggested for the realization

A Dual-Polarized Reconfigurable Reflectarray Antenna Based on a Symmetrically Rotated Sub-Array

open access: yesIEEE 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.

An active viscoelastic metamaterial for isolation applications [PDF]

open access: yes, 2014
Metamaterials are of interest due to their ability to produce novel acoustic behaviour beyond that seen in naturally occurring media. Of particular interest is the appearance of band gaps which lead to very high levels of attenuation within narrow ...
