Abstract
This paper includes a metamaterial design at THz range, explicitly useful as an absorber. It is composed of three layers with top and bottom are to be gold and separated by a dielectric material in between. The structure provides 100% at a lower frequency of 0.846 THz and 98.6% at a higher frequency of 2.12 THz. The proposed Complementary Split Ring Resonators (CSRR) shows a tuning range from 2.12 to 2.16 THz. The CSRR parameter is optimized to get dual resonance frequency. The proposed structure provides a quality factor of 19.2 at a lower band frequency and 19.56 at an upper band frequency.
