Abstract

Ultra sensitive metamaterial-based absorber (MA) which acts as a strong dual-band resonator is designed and constructed. The proposed model is based on symmetric ring resonator with gaps and octa-star strip (OSS) which allows maximization in the absorption at the resonances. Two maxima in the absorption are experimentally and numerically obtained with good agreement. The numerical studies verify that the dual-band MA can provide perfect absorption at wide angles of polarization and incidence waves. The proposed model can easily be used in many potential application areas such as security systems, sensors, medical imaging technology, and so on.
