Thin wideband infrared metamaterial absorber with coplanar metallic patches of different sizes
(Institute of Electrical and Electronics Engineers Inc., 2016)
Infrared absorber concept is a vibrant research topic because of the importance of real world applications such as infrared detectors, thermal coolers and energy harvesters. In this paper, we propose and numerically analyze ...
Broadband one way propagation via dielectric waveguides with unequal effective index
(Institute of Electrical and Electronics Engineers Inc., 2014)
We present an efficient approach for broad band one way propagation of light by parallel and unequal dielectric waveguides leading different effective phase shifts. Three dimensional numerical simulations show that 30% ...
Wide bandwidth absorption in the MWIR region using a thin and simple metamaterial absorber
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of ...
