Broadband terahertz absorber based on Dirac semimetal with tunable working bandwidth
A broadband metamaterial absorber (MA) based on bulk Dirac semimetal (BDS) with the property that the working bandwidth can be tuned is proposed. By changing the pattern on the top layer, the working band is expanded from narrowband to broadband. Interestingly, the working band over 90% absorption c...
