GOALI: Dynamically Tunable Low-Loss Active Metamaterials For Wireless Applications

目标该项目的总体目标是开发快速（~纳秒）宽带可调、低损耗、物理尺寸小、基于超材料的RF前端元件，与工业上正在开发的数字RF收发器概念兼容，用于各种商业和军事应用。 我们将专注于基于超导体元件的新型超材料，以形成极低的插入损耗，物理和电气小，高度可调谐的结构，用于下一代RF电子器件。 这些超材料将使我们能够提高性能，同时降低在宽带、多频带上工作的天线的尺寸和特征，并允许动态实时调谐。 这项工作将首次将约瑟夫森效应纳入超材料，从而开发超材料的全新应用，并测试几个高风险的理论预测。 更广泛的影响拟议的工作调查和促进超材料的应用射频和微波行业。 这些发展将通过创造高科技就业机会、改善无线通信和对生活质量产生积极影响，对社会产生直接和可衡量的价值。 PI有扩大代表性不足群体参与的历史（目前研究小组的50%是代表性不足群体的成员），并参与了许多外展活动。 这些活动将创造新的伙伴关系，合作和设施，将改变超导超材料领域的景观。 研究结果将通过出版物、国际会议上的讲座和海报、一个研究网站以及PI和学生继续开展的广泛外联活动进行传播。

ObjectiveThe overall goal of this project is to develop fast (~nanosecond) tunable-over-a-wide-band, low-loss, physically small, metamaterial-based RF front-end elements compatible with Digital-RF transceiver concept being developed in industry for a variety of commercial and military applications. We will focus on novel metamaterials based on superconductor elements to form extremely low insertion loss, physically and electrically small, highly tunable structures for the next generation of RF electronics. These metamaterials will allow us to increase performance while decreasing size and signature of antennas operating over wide bands, multibands and allowing dynamic real-time tuning. Intellectual MeritThe work will include the Josephson effect into metamaterials for the first time, leading to development of radical new applications of metamaterials and test several high-risk theoretical predictions. Broader ImpactsThe proposed work investigates and promotes applications of metamaterials for the RF and microwave industry. These developments will be of direct and measurable value to society through the generation of high-tech jobs, improvement of wireless communications, and a positive impact on quality of life. The PI has a history of broadening the participation of underrepresented groups (currently 50% of the research group are members of underrepresented groups), and is involved in numerous outreach activities. These activities will create new partnerships, collaborations, and facilities that will alter the landscape of the superconducting metamaterials field. The results will be disseminated through publications, talks and posters at international conferences, a research web site, and continuation of the extensive outreach activities by the PI and students.
