摘要：

Absorber has highly potential application in the military. However, most approaches suffer from very large size at low frequency and limited bandwidth. In this article, we solve these issues via combining the ITO film and cutting metal wire, with the former satisfying the novel impedance matching theory and the latter exhibiting resonant property. At last, we achieve ultra-broadband and high- efficiency absorption, especially at lower frequency range, from 2.4 GHz to 17.3 GHz. Our findings can realize ultra-broadband meta-devices.
