Comment on “Design and Characterization of an Ultrabroadband Metamaterial Microwave Absorber”
IEEE Photonics Journal, 2020 The authors have proposed an Ultrabroadband Metamaterial Microwave Absorber. The authors have claimed that the proposed structure is metamaterial absorber. We have recognized that the designed structure is not a metamaterial absorber because of ignorance

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 AbstractIn 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.

Study on Temperature Adjustable Terahertz Metamaterial Absorber Based on Vanadium Dioxide
IEEE Access, 2020 In the study of modern optics, the work of terahertz metamaterial absorbers is mostly multi-band perfect absorbers and ultra-wideband perfect absorbers. In contrast, in practical applications, metamaterial absorbers with adjustable resonance frequency or

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.

CMOS compatible metamaterial absorbers for hyperspectral medium wave infrared imaging and sensing applications [PDF]
, 2018 We experimentally demonstrate a CMOS compatible medium wave infrared metal-insulator-metal (MIM) metamaterial absorber structure where for a single dielectric spacer thickness at least 93% absorption is attained for 10 separate bands centred at 3.08, 3 ...

Dual broadband metamaterial absorber
Optics Express, 2015 We propose polarization-independent and dual-broadband metamaterial absorbers at microwave frequencies. This is a periodic meta-atom array consisting of metal-dielectric-multilayer truncated cones. We demonstrate not only one broadband absorption from the fundamental magnetic resonances but additional broadband absorption in high-frequency range using ...
