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.

Hyperbolic metamaterial interfaces: Hawking radiation from Rindler horizons and the "end of time" [PDF]
, 2011 Extraordinary rays in a hyperbolic metamaterial behave as particle world lines in a three dimensional (2+1) Minkowski spacetime. We analyze electromagnetic field behavior at the boundaries of this effective spacetime depending on the boundary orientation.

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 ...

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 ...
