The recent advancement towards THz system design and development, spectroscopy non-destructive testing (NDT) fascinates researchers’ attention in the development of absorbing coating composites to counter stealth technologies shielding from radiation. Conductive fillers based absorber have emerged as a solution their properties can be tuned with change filler loading. In this study, several mul...

Terahertz metamaterial biosensor is a label-free affinity sensor that enhances the strength of local electromagnetic field. It extremely sensitive to changes in dielectric constant surrounding environment, thereby providing new method detecting micro or trace biological samples. In this work, highly terahertz refractive index absorber for sample proposed. The consists two concentric open metal ...

Graphene is a powerful 2-D matter with the capability of extraordinary transparency, and tunable conductivity employed in emerging optoelectronics devices. In this article, design an electrically graphene-based perfect terahertz absorber proposed evaluated numerically. The introduced structure composed two graphene layers sharp absorption peak band. These are combline stripline separated by ins...
