چکیده
In this paper, we report a switchable ultra-wideband metamaterial absorber with polarization-insensitivity and wide-incident angle at THz band which is composed of VO 2 disk, polyimide dielectric substrate, gold ground plane. The results show that the absorption greater than 90% from 3.5–8 for temperature 300 K disappears when rises to 350 K. property our proposed insensitive polarization states angles it can withhold high more 80% angles, up 60° TE mode TM mode. wideband mechanism elucidated using an effective medium surface current analysis.

In this paper, an incident angle- and polarization-insensitive metamaterial absorber is proposed for X-band applications. A unit cell of the proposed absorber has a square patch at the centre and four circular sectors are rotated around the square patch. The vertically and horizontally symmetric structure of the unit cell enables polarization-insensitivity. The circular sector of the unit cell ...

متن کاملWideband-Switchable Metamaterial Absorber Using Injected Liquid Metal
Metamaterial absorbers can provide good solutions for radar-cross-section (RCS) reduction. In spite of their attractive features of thinness, lightness, and low cost, resonant metamaterial absorbers have a drawback of narrow bandwidth. For practical radar applications, wideband absorbers are necessary. In this paper, we propose a wideband-switchable metamaterial absorber using liquid metal. In ...
