absorbers for various applications, such as electromagnetic stealth, photodetection, and …

Designing broadband absorbers with only one metamaterial layer operating in the terahertz
band is a relatively difficult challenge. In this paper, we proposed and investigate a …

Broadband absorbers with multiple absorption bands, adjustable properties and simple
configurations in the terahertz region are quite scarce and hold competent aptitude. In this …
