Energy and exergy analyses of hydrogen production by coal gasification
(Elsevier Ltd, 2017)
In this study, we examine an integrated coal based gasification system developed for hydrogen production and power generation. The proposed plant consists of air separation unit, gasification unit, gas cooling and cleaning ...
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 ...
