Terahertz Absorbing Metamaterials for detection systems

本报告探讨了超材料在未来太赫兹探测系统中的潜在用途。通过设计一种能实现太赫兹近乎统一吸收的超材料，就有可能制造出宽带和精确的探测器。诸如此类的设备可以用于光谱测量，也可以用于已经使用太赫兹频率的行业内的潜在应用，例如皮肤病学，医学成像和制药行业以及安全和通信。本文研究了超材料结构的设计和模拟，以寻找不同设计和配置的最佳吸收，发现使用分裂环谐振器超材料可以实现统一吸收。该项目的目的是为太赫兹应用设计具有改进响应时间和灵敏度的超材料探测器。

This report looks into the potential uses of meta-materials in future detection systemsfor terahertz. By designing a meta-material which achieves near unity absorption of terahertzit would be possible to create both broadband and precise detectors. Devices suchas these could be used in spectroscopy measurements as well as potential applicationswithin industry where terahertz frequencies are already used, such as dermatology, medicalimaging and the pharmaceutical industry as well as security and communication.This report looks into the design and of the simulations of meta-material structures tofind optimal absorption for different designs and configurations, It is found it is possibleto achieve unity absorption using split ring resonator meta-materials. The aim of thisproject are to design meta-material detectors for terahertz applications with improvedresponse time and sensitivity.
