Choudhury B., Menon A., Mohan Jha R. Active terahertz metamaterial for biomedical applications

Springer, 2016. — 63 p. — (Springer Briefs in Electrical and Computer Engineering. Computational Electromagnetics).Terahertz spectroscopy is gaining momentum as a tool for imaging in the field of biomedical engineering. This increase in popularity is due to the non-invasive, non-ionizing nature of terahertz radiation coupled with its propagation characteristics in water, which allows the operator to obtain high-contrast images of skin cancers, burns, etc., without detrimental effects. In order to tap this huge potential, researchers are aiming to build highly efficient biomedical imaging systems by introducing radiation (THz) absorbers into biomedical detectors. The biggest challenge faced in the fulfilment of this objective is the lack of naturally occurring dielectrics, which is combated with the use of artificially engineered resonant materials called metamaterials.Active Terahertz Metamaterial for Biomedical Applications.Terahertz Radiation.
