Broadband LWIR and MWIR metamaterial absorbers with a simple design topology: Almost perfect absorption and super-octave band operation in MWIR band
(OSA - The Optical Society, 2017)
Infrared absorbers are essential structures in the design of thermal emitters and thermal infrared imagers. In this study, we propose simple topologies of wideband metamaterial absorbers operating in the long-wave infrared ...
Ultra-broadband long-wavelength infrared metamaterial absorber based on a double-layer metasurface structure
(OSA - The Optical Society, 2017)
In this paper, we report a metamaterial absorber design that achieves a broad absorption band encompassing the whole long-wavelength infrared (LWIR) region. The structure consists of two parallel metasurfaces buried in an ...
Efficient and broadband guided wave one-way mode-order conversion with theoretical and numerical analysis
(Optical Society of American (OSA), 2013)
In this article, an efficient method of asymmetric conversion of guided modes is investigated. From a basic excitation consisting of (mainly) the lowest-order mode of the input multimode strip waveguide, we achieve a ...
Polymer-graphene hybrid stabilized ruthenium nanocatalysts for the dimethylamine-borane dehydrogenation at ambient conditions
(Elsevier B.V., 2019)
In this work, we reported a new catalyst consistent of graphene oxide (GO) – poly(N-vinyl-2-pyrrolidone) (PVP) hybrid supported ruthenium nanoparticles and called as Ru@GO-PVP. The GO-coupled PVP nanosheets were prepared ...
