Abstract: A broadband metamaterial absorber with high absorption simultaneously in mid-wave infrared (MWIR) and long-wave infrared (LWIR) was proposed. In the MWIR, the absorption higher than 0.8 is from 4 to 6.3 µm, while the absorption in… read more here.

Abstract: We proposed a metamaterial absorber composed of an array of trapezoid multilayered grating Au and InP on top of an opaque substrate, which covers two atmosphere-transparent-window bands with appropriate modulation of geometric parameters. The absorption… read more here.
