Not Accessible

Your library or personal account may give you access

Abstract

We report a broadband terahertz metamaterial absorber with two nested back-to-back split-ring resonators constituting a single planar resonator. Bandwidths of 0.66THz and 0.98THz with the absorptivity above 0.8 and 0.6 were experimentally obtained respectively.
