Nanostructure-enhanced infrared spectroscopy

Nanophotonics, 2021
While infrared spectroscopy is a powerful technique that provides molecular information such as chemical constituents and chemical structures of analytes, it suffers from low absorption cross-section resulting in low sensitivity and poor signal-to-noise ...

Advanced application of flexible metamaterials at visible frequencies [PDF]

, 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.

Electro-mechanical light modulator based on controlling the interaction of light with a metasurface

Scientific Reports, 2017
We demonstrate a reflective light modulator, a dynamic Salisbury screen where modulation of light is achieved by moving a thin metamaterial absorber to control its interaction with the standing wave formed by the incident wave and its reflection on a ...

Bianisotropic Effective Parameters of Optical Metamagnetics and Negative-Index Materials [PDF]

, 2011
Approaches to the adequate homogenization of optical metamaterials are becoming more and more complex, primarily due to an increased understanding of the role of asymmetric electrical and magnetic responses, in addition to the nonlocal effects of the ...

Superconducting metamaterials [PDF]

Applied Physics Letters, 2005
Evanescent wave amplification has been predicted under the ideal condition that the index of refraction, n=−1+i0 precisely, but is difficult to observe in practice because current metamaterials suffer from high losses. We present experimental results on a metamaterial that employs superconducting Nb metals and low-loss dielectric materials.

Long-metallic-strip array with parasitic rings: an efficient metasurface for dual-broadband electromagnetic window at large angles

Nanophotonics
The long-metallic-strip (LMS) array proposed by J. B. Pendry has been widely studied in electromagnetic windows. However, it could only work for the single-band window, not the dual-band one, due to the plasma-like oscillation attenuating with increasing
