Abstract
An ultrathin metal-free broadband absorber covering the far-infrared region is designed and implemented. A graphite resonator and reflector are used to provide the dual-resonance with merged spectrum. The graphite resonator is perturbed to improve the impedance bandwidth of the absorber at both the resonances. This helps in obtaining the wide and merged resonance to provide the wide absorption spectrum by maintaining the level of absorption more than 90%. The electromagnetic resonances taking place in the absorber structure are the reason behind the operation of the proposed absorber hence the circuit model analysis is carried out to validate its operation. Moreover, the shielding effectiveness of the absorber can vary from 40 to more than 150 dB proving its capability to be utilized in EM shielding, packaging and thermal storage applications in lower THz frequency band with ultrathin structure.
