Objective: This project focuses on the fundamental theoretical and experimental study of metamaterial covers, operating as cloaks to suppress the otherwise inevitable disturbance that near-field sensors, imagers and absorbers produce on their surroundings. These findings will be aimed at advancing near-field measurements and imaging techniques, and increasing the efficiency of green-energy devices. Furthermore, these research concepts will be combined with a number of outreach and educational activities, aimed at integrating metamaterial research and education, with special emphasis on diversity and minorities.Intellectual Merit: The project applies the unique property of plasmonic metamaterial shells to tunnel, capture and extract energy, combined with minimized scattering. In near-field probing applications, this may realize sensors that measure and image without perturbing their own measurement, drastically improving their overall performance. Moreover, this technology holds the potential to match, tune and maximize the efficiency of energy-harvesting devices by eliminating scattering, reflections andunwanted coupling. Finally, this project will establish thin-film conformal metamaterial technology also suited for a variety of other applications, from radio to optical frequencies.Broader Impacts: These results may substantially improve biomedical measurements and the efficiency of absorbing semiconductor devices. Moreover, the educational plan broadens the project?s impact through various activities, including the creation of a website, combining teaching resources on metamaterials with cutting-edge research updates, and the organization of a student symposium on metamaterials. These efforts will fill the gap between the considerable research activity on metamaterials and its currently limited educational extent, broadening the impact of these exciting topics to all society.

目的：本项目侧重于超材料覆盖物的基础理论和实验研究，作为斗篷来抑制近场传感器、成像仪和吸收器对其周围环境产生的不可避免的干扰。这些发现将旨在推进近场测量和成像技术，并提高绿色能源设备的效率。此外，这些研究概念将与一些外联和教育活动相结合，旨在将超材料研究和教育结合起来，特别强调多样性和少数群体。智力优势：该项目将等离子体超材料壳的独特特性应用于隧道，捕获和提取能量，并结合最小化散射。在近场探测应用中，这可以实现传感器在不干扰其自身测量的情况下进行测量和成像，从而大大提高其整体性能。此外，该技术通过消除散射、反射和不必要的耦合，具有匹配、调整和最大化能量收集设备效率的潜力。最后，该项目将建立薄膜共形超材料技术，也适用于各种其他应用，从无线电到光学频率。更广泛的影响：这些结果可能会大大改善生物医学测量和吸收半导体器件的效率。此外，教育计划拓宽了项目。通过各种活动，包括创建一个网站，将超材料的教学资源与前沿研究更新结合起来，以及组织一个关于超材料的学生研讨会。这些努力将填补超材料的大量研究活动与目前有限的教育程度之间的空白，扩大这些令人兴奋的话题对全社会的影响。
