CAREER: Liquid Radio Frequency Electronics

本研究的目的是为基于液体的高频电路和天线同时在电、热和机械能领域进行优化提供新的基本见解。其方法是合成液体微波器件和电路，能够利用其液体性质来适应和冷却自己。智能优势：尽管研究人员已经解决了与异质集成三维电路相关的许多挑战，但热管理仍然是此类体系结构中最困难的问题之一。这项研究融合了高频电子学和微流体这两项强大的技术，提供了一种有吸引力的解决方案，大幅提高了电源效率和灵活性。特别是，设想的液体射频设备将提供显著增强的适应性，因为液体具有重新配置其形状的自然能力。此外，它们将使用相同的液体材料(介质和金属)来调整其性能和冷却自己。广泛的影响：这项努力的结果预计将成为未来一代三维多功能电路的关键使能技术。这将构成一个令人信服的证明，电气和热设计需要并可以合并到一个电热联合设计过程中。新的设计规则预计将不断演变，并可用于下一代设计软件。这项研究还与一项教育计划相结合，该计划侧重于吸引和留住国内少数民族学生，并鼓励本科生在职业生涯早期参与研究活动。这一努力将与普渡大学建立的适当的服务学习和以项目为导向的计划很好地协调。

AbstractECCS-0747766Dimitrios Peroulis, Purdue University The objective of this research is to provide new fundamental insights for liquid-based high-frequency circuits and antennas simultaneously optimized in the electrical, thermal and mechanical energy domains. The approach is to synthesize liquid microwave devices and circuits with the ability to exploit their liquid nature for adapting and cooling themselves.Intellectual merit: Although researchers have already addressed many challenges associated with heterogeneously integrated three-dimensional circuits, thermal management remains one of the most difficult problems in such architectures. This research merges two powerful technologies, high-frequency electronics and microfluidics, to provide an attractive solution with substantial improvements in power efficiency and agility. In particular, the envisioned liquid radio frequency devices will offer considerably enhanced adaptivity because of the natural ability of a liquid to reconfigure its shape. Furthermore, they will utilize the same liquid materials (dielectrics and metals) for both tuning their performance and cooling themselves.Broader impacts: The outcome of this effort is expected to be a critical enabling technology for the future generation of three-dimensional multifunctional circuits. This will constitute a convincing demonstration that electrical and thermal designs need and can be combined into one electro-thermal co-design process. New design rules are expected to evolve and become available into the next generation design software. This research is also integrated with an educational plan focused on attracting and retaining domestic minority students and in engaging undergraduate students to research activities early in their careers. This effort will be well-coordinated with appropriate established service-learning and project-oriented programs at Purdue University.
