THz-metamaterial absorbers [PDF]
Advances in Natural Sciences: Nanoscience and Nanotechnology, 2013 An ultrabroad-band metamaterial absorber was investigated in mid-IR regime based on a similar model in previous work. The high absorption of metamaterial was obtained in a band of 8?11.7?THz with energy loss distributed in SiO2, which is appropriate potentially for solar-cell applications.

Broadband microwave coding metamaterial absorbers [PDF]
Scientific Reports, 2020 Abstract In this paper, a broadband metamaterial microwave absorber is designed, simulated and measured. Differently from the traditional method which is only based on unit cell boundary conditions, we carried out full-wave finite integration simulations using full-sized configurations. Starting from an elementary unit cell structure,

Lithography-free metamaterial absorbers: opinion
Optical Materials Express, 2022 Although advancement in nanofabrication provides the opportunity to realize nanoscale geometries with high resolutions, the scalability and repeatability issues limit their large-scale applications. Lithography-free metamaterial absorbers (LFMAs) are a potential route for the upscaling of these designs.
