Contribution

The paper presents a new metamaterial absorber that operates effectively across multiple Terahertz frequency bands in TE and TM modes, suitable for 6G technology.

Findings

Effective absorption in 0.5-1.1 THz range

Dualband and tripleband operation achieved

Works as a perfect absorber in TM mode at higher WR1 frequencies

Abstract

Frequency Band of 0.5 THz to 1.1 THz (WR1.5 and WR1) is one of the promising bands when it comes to 6G. In this paper, we propose a novel metamaterial absorber suitable to be used at lower WR1 frequencies in TE mode. Alternatively, the design can be used as a strong absorber at lower Terahertz frequencies. In addition, when used in TM mode the absorber works as a perfect absorber at higher WR1 band.
