Metamaterial Absorber - Springer Nature

Triple-band terahertz metamaterial absorber using surface structure of two metallic split rings of same-size connected by a non-centrally-placed metallic strip

This patterned surface structure is made up of two identical-sized gold split rings joined by a gold strip, which is marginally deviated from the geometric center, resulting in uneven sizes on both left and right sides of the surface structure. The number of absorption peaks and resonance frequencies of these peaks can be adjusted by changing the deviation location of the connecting gold strip and the parameters of the two gold split rings. In addition, the two gold split rings' width and length will alter the resonance frequencies of the three absorption peaks. These findings reveal that the recommended THz metamaterial absorbers have broad application opportunities in sensing, detection, imaging, and other fields.
