Flexible metamaterials for advanced photonics applications

, 2014
We present our recent results on the design, fabrication and applications of flexible metamaterials in the visible and near infrared range. In particular, we demonstrate broad angle spectral filtering for lab-on-fibre applications, the realisation of ...

Electromagnetic metamaterial agent

Light: Science & Applications
AbstractMetamaterials have revolutionized wave control; in the last two decades, they evolved from passive devices via programmable devices to sensor-endowed self-adaptive devices realizing a user-specified functionality. Although deep-learning techniques play an increasingly important role in metamaterial inverse design, measurement post-processing ...

Review Article: The weak interactive characteristic of resonance cells and broadband effect of metamaterials

AIP Advances, 2014
Metamaterials are artificial media designed to control electromagnetic wave propagation. Due to resonance, most present-day metamaterials inevitably suffer from narrow bandwidth, extremely limiting their practical applications.

Numerical investigation of Fano resonances in metamaterials with electric asymmetry [PDF]

, 2011
The excitation of high quality factor asymmetric Fano-type resonances on a double layer metafilm structure is investigated through numerical simulation. The paper demonstrates that it is possible to design simple structures capable to sustain a very high

Evolution of the Electromagnetic Manipulation: From Tunable to Programmable and Intelligent Metasurfaces

Micromachines, 2021
Looking back on the development of metamaterials in the past 20 years, metamaterials have gradually developed from three-dimensional complex electromagnetic structures to a two-dimensional metasurface with a low profile, during which a series of ...

Broadband electromagnetic cloaking with smart metamaterials [PDF]

Nature Communications, 2012
The ability to render objects invisible with a cloak that fits all objects and sizes is a long-standing goal for optical devices. Invisibility devices demonstrated so far typically comprise a rigid structure wrapped around an object to which it is fitted.

Advanced application of flexible metamaterials at visible frequencies

, 2015
The authors acknowledge support by EPSRC (EP/I004602/1 and EP/J004200/1).Flexible metamaterials (FMMs) at optical frequencies can conform to a wide range of target geometries whilst allowing their optical properties to be tuned post-fabrication.

Metamaterials for light rays: ray optics without wave-optical analog in the ray-optics limit [PDF]

, 2009
Volumes of sub-wavelength electromagnetic elements can act like homogeneous materials: metamaterials. In analogy, sheets of optical elements such as prisms can act ray-optically like homogeneous sheet materials.

Trapped-Mode Resonances in Planar Metamaterials with High Structural Symmetry

, 2008
We propose a new type of planar metamaterials that can support high-Q electromagnetic modes, namely trapped modes, excitation of which is polarization ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...
