Electromagnetic Response of Finite Terahertz Metafilm Arrays Excited on Total Internal Reflection Boundaries

Recent Advances in the Development of Materials for Terahertz Metamaterial Sensing

“…[ 72 ] Another well‐known technique that is capable of overcoming the negative effects produced by the polar solvent absorption in the terahertz regime is attenuated total reflection (ATR). [ 73 ] Tanaka and co‐workers developed Au terahertz metamaterials using split‐ring resonators with increased resonance, as shown in the corresponding ATR spectrum (Figure 7d). [ 73,74 ] Recently, Ahmadivand et al.…”

“…[ 73 ] Tanaka and co‐workers developed Au terahertz metamaterials using split‐ring resonators with increased resonance, as shown in the corresponding ATR spectrum (Figure 7d). [ 73,74 ] Recently, Ahmadivand et al. designed an approach to detect SARS‐CoV‐2 (Severe Acute Respiratory Syndrome Coronavirus 2) virus protein at low level using a toroidal THz metamolecule which makes COVID‐19 (Corona Virus Disease 2019) infection diagnosis easy.…”

“…The TMS methods based on the SPPs generated on the surfaces of common and noble metals (Au, Ag, Cu, and Al) have been extensively studied by researchers; [ 63–85 ] however, they suffer from large intrinsic losses and nontunability. Recently, 2D single‐element materials (such as graphene, carbon nanotubes (CNTs), and black phosphorus (BP)) have attracted considerable attention as potential TMS materials due to their unique electrical and optical properties.…”
