点击翻译按钮获取中文摘要

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.
