Abstract
A meta-surface that absorbs waves from all directions of incidence can be realized if the surface impedance is made to vary as a function of incidence in a specific manner. In this paper, a terahertz meta-surface with left-handed characteristics for high absorbing applications is discussed. The designed small absorber unit was developed by cross-metallic connection of two metal strips printed on epoxy resin fibre material. Finite integration technique-based electromagnetic simulator Computer Simulation Technology Microwave Studio was utilized to simulate and investigate the proposed design. The proposed meta-surface shows resonance at 39.19 THz, 58.47 THz and 77.80 THz and left-handed characteristics at 15.3 THz and 87.7 THz respectively. In addition, the structure of the absorber shows the highest absorption peaks of 99.6% and 89.5% at 16.4 THz and 75.8 THz respectively.
