Proof of Concept Study of Active Aperture Antennas

项目编号：ECS-9612567 PI姓名/机构：Gregory Washington/俄亥俄州立大学引用的非裔美国PI在俄亥俄州立大学任教的第一年申请了研究计划基金，以启动一个基于压电薄膜分布式执行器的新型自适应孔径天线项目。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。这是一个非常出色且细致的建议，它侧重于概念验证，包括三个步骤的理论和实验设计：(1)建立表面形状与辐射方向图的关联模型。这将为未来提案的概念可行性提供强有力的支持。提出的建模是PI已经发表的原始工作的扩展。(2)有源天线制造：中心问题涉及到将压电薄膜粘合到可接受的衬底上，这将是本节的重点。强调可扩展到工业的方法。(3)天线表面偏转测试。这将为概念的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今后的提案提供非常坚实的基础。良好的知识和关键主题的选择是由PI证明。俄亥俄州立大学提供的资源也很好。我强烈建议按提议的数额$17,970.00提供资金。

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.
