Proof of Concept Study of Active Aperture Antennas

提案编号： ECS-9612567 主要研究者姓名/机构： 格雷戈里华盛顿/俄亥俄州州立大学 参考的非裔美国人PI在他的第一年作为教师在俄亥俄州州立大学已要求研究规划补助金的资金，发起一项计划，以开发一种新的类的自适应孔径天线的压电薄膜分布式致动器的基础上。 压电薄膜是“智能材料”的一个例子。 这项工作如果成功，将真正彻底改变孔径天线的成像技术，并可能对医学成像产生影响。 这是一个很好的和仔细详细的建议，其重点是概念的理论和实验设计的证明，涉及三个步骤：（1）建模，以关联的表面形状与辐射图案。这将为今后提案中的概念可行性提供有力支持。建议的建模是PI已经发表的原始工作的扩展。 (2)有源天线制造：核心问题涉及压电薄膜与可接受的基底的粘合，这将是本节的重点。 强调了可扩展到工业的方法。 (3)水循环微波消融针表面偏转测试。 这将为概念可行性提供强有力的实验验证。 成功完成上述三个步骤将为未来的提案提供非常坚实的基础。 PI证明了对关键主题的良好知识和选择。 俄亥俄州州立大学提供的资源也很棒。 我强烈建议按拟议的17 970.00美元供资。

Proposal #: ECS-9612567 PI Name/Institution: Gregory Washington/ Ohio State University The referenced African American PI in his first year as faculty at Ohio State University has requested Research Planning Grant funds to initiate a program to develop a novel class of adaptive aperture antennas based on piezoelectric film distributed actuators. Piezoelectric films are one example of "smart materials". This work if successful will truly revolutionize imaging techniques in aperture antennas, with possible ramifications for medical imaging. This is an excellent and carefully detailed proposal which focuses on a proof of concept theoretical and experimental design involving three steps: (1) Modeling to correlate the surface shape with the radiation pattern. This will provide strong support for concept viability in future proposals. The proposed modeling is an extension of original work which the PI has already published. (2) Active antenna fabrication: The central problem involves bonding of the piezoelectric film to an acceptable substrate and this will be the focus of this section. Methods which are scaleable to industry are emphasized. (3) Antenna surface deflection testing. This will provide strong experimental verification of concept viability. Successful completion of the above three steps will provide a very strong foundation for a future proposal. A good knowledge and selection of crucial topics is evidenced by the PI. Resources provided by Ohio State University are also excellent. I strongly recommend funding at the proposed amount of $17,970.00.
