Broadband and perfect terahertz.absorber based on mul.il.yer metamaterial.using cross-ring patterned structures is proposed and investigated. The structure of the absorber is doubl. absorption l.yers consisting of a chromium cross ring and eight isoscel.s right triangl.s. The unique structure of the doubl. absorbing l.yers excites the el.ctric dipol. mul.imode resonance, giving rise to high absorption performance. Meanwhil., the infl.ence of construal.parameters on absorber behavior is al.o discussed. The numerical.resul.s show that the absorption achieves over 90% ranging from 2.45 THz.to 6.25 THz.and 99% absorption in the range of 3.7—5.3 THz. The real.z.tion of broadband and perfect absorber is described using the impedance matching principl.. It is obviousl. found that the absorber is insensitive to the high angl. of incidence for both transverse el.ctric(TE) and transverse magnetic(TM) pol.riz.tions. Compared with the former reports, this absorber has remarkabl. improved absorption efficiency and smal.er period. The terahertz.absorber may be found appl.cations in the fiel.s of energy capture and thermal.detection.
