AbstractRF/Microwave components and devices using micro-/nano machined metamaterial:The objectives of this research are (1) to investigate and implement low loss, multidimensional high quality metamaterials using advanced micromachining and nanotechnology, and (2) to translate the developed metamaterial technologies to highly efficient, compact, and multifunctional radio frequency (RF) devices and components. Metamaterials due to their unique properties have a potential to drastically impact RF devices. Compact and multifunctional metamaterial RF devices have recently emerged. However, several unsolved issues hamper the practical applications of current metamaterial technology: reduction of material loss, construction of three dimensional (3-D) structures, and development of cost-effective fabrication processes. The intellectual merit for this research includes: 1) a novel air-lifted architecture and a lateral nano lamination conductor architecture to respectively reduce dielectric loss and conductor loss of metamaterials, 2) the development of 3-D micro-/nano fabrication technique development, and 3) a new class of multifunctional RF devices utilizing the developed metamaterials such as a flexible invisibililty cloak, a compact low loss dual band coupler, and a compact high efficient dual band antenna. The envisioned micro-/nano machined metamaterial and its RF device applications will provide a major breakthrough in the field.The broad impacts of the proposal include integrated education and research at various fronts, such as new courses, minority and undergraduate research support, and outreach activities at the University at Buffalo. Also supported will be an on-line course encompassing three State University of New York campuses. The technical and societal impacts of this research will occur in diverse areas such as telecommunications, defense, microelectronics, and medical imaging.

本研究的目标是：(1)利用先进的微机械加工和纳米技术研究和实现低损耗、多维高质量的超材料；(2)将开发的超材料技术转化为高效、紧凑和多功能的射频(RF)器件和部件。超材料由于其独特的性质，有可能对射频器件产生巨大的影响。最近出现了紧凑型和多功能的超材料射频器件。然而，一些尚未解决的问题阻碍了当前超材料技术的实际应用：减少材料损失，构建三维(3D)结构，以及开发具有成本效益的制造工艺。这项研究的智能价值包括：1)一种新型的空气提升结构和横向纳米叠层导体结构，分别降低了超材料的介电损耗和导体损耗；2)三维微纳制造技术的发展；3)利用所开发的超材料研制的新型多功能射频器件，如柔性隐形斗篷、紧凑的低损耗双频耦合器和紧凑的高效双频天线。设想的微纳加工超材料及其射频器件应用将在该领域取得重大突破。该提案的广泛影响包括多个方面的综合教育和研究，如新课程、少数族裔和本科生研究支持，以及布法罗大学的外展活动。还将支持一个包括纽约州立大学三个校区的在线课程。这项研究的技术和社会影响将出现在不同的领域，如电信、国防、微电子和医学成像。
