Active Terahertz Metamaterial for Biomedical Applications by Balamati Choudhury, Arya Menon, Rakesh Mohan Jha

By Balamati Choudhury, Arya Menon, Rakesh Mohan Jha

This publication describes a metamaterial-based lively absorber for power biomedical engineering purposes. Terahertz (THz) spectroscopy is a crucial software for imaging within the box of biomedical engineering, as a result of the non-invasive, non-ionizing nature of terahertz radiation coupled with its propagation features in water, which permits the operator to procure high-contrast photographs of epidermis cancers, burns, and so forth. with out hazardous results. that allows you to faucet this large power, you will need to construct hugely effective biomedical imaging structures by means of introducing terahertz absorbers into biomedical detectors. the largest problem confronted within the fulfilment of this aim is the shortcoming of obviously taking place dielectrics, that's triumph over with using artificially engineered resonant fabrics, viz. metamaterials. This booklet describes this type of metamaterial-based energetic absorber. The layout has been optimized utilizing particle swarm optimization (PSO), finally leading to an ultra-thin lively terahertz absorber. The absorber indicates close to cohesion absorption for a tuning diversity of terahertz (THz) application.
