Broadband microwave coding metamaterial absorbers. [PDF]
Sci Rep, 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.

Plasmonic and metamaterial structures as electromagnetic absorbers [PDF]
Laser & Photonics Reviews, 2014 AbstractElectromagnetic absorbers have drawn increasing attention in many areas. A series of plasmonic and metamaterial structures can work as efficient narrowband absorbers due to the excitation of plasmonic or photonic resonances, providing a great potential for applications in designing selective thermal emitters, biosensing, etc.

Perfect Metamaterial Absorber [PDF]
Physical Review Letters, 2008 We present the design for an absorbing metamaterial element with near unity absorbance. Our structure consists of two metamaterial resonators that couple separately to electric and magnetic fields so as to absorb all incident radiation within a single unit cell layer. We fabricate, characterize, and analyze a metamaterial absorber with a slightly lower

Multispectral metamaterial absorber [PDF]
Optics Letters, 2014 We present the simulation, implementation, and measurement of a multispectral metamaterial absorber (MSMMA) and show that we can realize a simple absorber structure that operates in the mid-IR and terahertz (THz) bands. By embedding an IR metamaterial absorber layer into a standard THz metamaterial absorber stack, a narrowband resonance is induced at a

Broadband absorber with dispersive metamaterials
Nanophotonics, 2023 Abstract A broadband absorber that utilizes a dispersive metamaterial and covers the entire microwave X‐band (8–12 GHz) is proposed in the present study. An ideal absorber attached to the surface of a perfect electric conductor requires the permittivity of the absorbing layer to be anomalously dispersive in the targeted broad ...

Metamaterial Electromagnetic Wave Absorbers [PDF]
Advanced Materials, 2012 AbstractThe advent of negative index materials has spawned extensive research into metamaterials over the past decade. Metamaterials are attractive not only for their exotic electromagnetic properties, but also their promise for applications. A particular branch–the metamaterial perfect absorber (MPA)–has garnered interest due to the fact that it can ...

Spectrum Absorbency of Metamaterial Perfect Absorber
The International Journal of Integrated Engineering, 2022 A triple-band metamaterial perfect absorber was introduced. The single and simple structure based on gold-bar shaped was designed on the 0.018λ Taconic TLY-5. The gold-bar shaped was designed horizontal initially was then being rotated anti-clockwise from0oto 90oto analyze and understand the change of absorption graph.

Manually tunable ventilated metamaterial absorbers [PDF]
Applied Physics Letters, 2021 For most acoustic metamaterials, once they have been fabricated, their operating frequencies and functions cannot be adjusted, which is an intrinsic barrier for the development of realistic applications. The study to overcome this limit has become a significant issue in acoustic metamaterial engineering.
