Terahertz Metamaterial Absorbers for Sensing Applications

Dear Colleagues,

Metamaterials are a recent development in electromagnetics that have immense potential applications. Metamaterial absorbers are a class of metamaterial structures that can absorb all incident electromagnetic radiation. Terahertz metamaterial absorbers operate in the terahertz band. The terahertz band is not as thoroughly explored as the microwave and the optical bands—a gap infamously known as the “terahertz gap”. However, many researchers are contributing to this domain, and these absorbers can also be used for sensing applications, such as refractive index sensing, analyte depth sensing, biomedical sensing, food quality sensing, gas detection, etc. The development of highly sensitive polarization- and incident-angle-independent designs is still a challenging topic of research.
