Application of Terahertz Wave Technology in the Biomedical Field

This paper introduces a sensing technology that utilizes terahertz (THz) wave with metal mesh resonant filters in the biomedical field. Due to the consistency of energy regions, it is expected to bring about the non-labeling detection of hydrogen bonding and/or intermolecular recognition, as well as antibody responses, etc. Regularly arranged metallic mesh can also be used to make effective use of the THz wave anomalous propagation and absorption characteristics (spoof surface plasmon) of specimens for biopolymer systems, which do not indicate characteristic absorption in the THz band. This paper introduces the THz wave absorption and propagation characteristics in metallic meshes designed for the THz sensing and for application to biomedical related specimens.
