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

By Balamati Choudhury, Arya Menon, Rakesh Mohan Jha

This ebook describes a metamaterial-based energetic absorber for power biomedical engineering functions. Terahertz (THz) spectroscopy is a vital software for imaging within the box of biomedical engineering, end result of the non-invasive, non-ionizing nature of terahertz radiation coupled with its propagation features in water, which permits the operator to acquire high-contrast photos of dermis cancers, burns, and so on. with no dangerous results. so as to faucet this massive capability, it is very important construct hugely effective biomedical imaging platforms by way of introducing terahertz absorbers into biomedical detectors. the largest problem confronted within the fulfilment of this goal is the shortcoming of clearly happening dielectrics, that's conquer with using artificially engineered resonant fabrics, viz. metamaterials. This publication describes any such metamaterial-based lively absorber. The layout has been optimized utilizing particle swarm optimization (PSO), ultimately leading to an ultra-thin lively terahertz absorber. The absorber exhibits close to harmony absorption for a tuning diversity of terahertz (THz) application.

This computational engine eliminates the need for manually determining the best structural parameters and is especially useful when the design equations are not well known. In addition to structural optimization, the computational engine was also used to determine the optimum inner ring rotational angles for a three element absorber array. This engine is capable of determining the rotational angles for different resonant frequencies. These values constitute a database which can be used for the rapid, adaptive tuning of the absorber array.

For optimization problems, the solutions can be prevented from falling into local minima by using global optimization strategies. • These methods yield cost-effective solutions to the user. Further, hybridization of soft computing methods may reduce the conventional simulation procedures up to some extent. • These methods are adaptive and can be scalable. 2 Background Theory 15 Abundant literature is available for implementation of genetic algorithm and micro-genetic algorithm for RAM optimization.
