Perfect Metamaterial Absorber [PDF]
Physical Review Letters, 2008 We present the design for an absorbing metamaterial element with near unity absorbance. Our structure consists of two metamaterial resonators that couple separately to electric and magnetic fields so as to absorb all incident radiation within a single unit cell layer. We fabricate, characterize, and analyze a metamaterial absorber with a slightly lower

Spatio-temporal characterization of ultrashort vector pulses
APL Photonics, 2021 Ultrafast vectorially polarized pulses have found many applications in information and energy transfer owing mainly to the presence of strong longitudinal components and their space-polarization non-separability.

Coding Metamaterials, Digital Metamaterials and Programming Metamaterials
, 2014 As artificial structures, metamaterials are usually described by macroscopic effective medium parameters, which are named as "analog metamaterials". Here, we propose "digital metamaterials" in two steps. Firstly, we present "coding metamaterials" that are composed of only two kinds of unit cells with 0 and phase responses, which we name as "0" and ...

Plasmonic anapole metamaterial for refractive index sensing
PhotoniX, 2022 Electromagnetic anapole mode is a nonradiative state of light originating from the deconstructive interference of radiation of the oscillating electric and toroidal dipole moments.

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 ...

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 ...
