US-India Cooperative Research: High Temperature Dielectric Studies on Advanced Materials in the High Frequency Region

该奖项支持美印合作研究，题为“高频区域先进材料的高温介电研究”。美国调查人员是宾夕法尼亚州立大学的迪内什·阿格拉瓦尔和迈克尔·拉纳根；印度调查人员是新德里印度理工学院的迪内什·杜布和古普塔。微波加工是一种被广泛接受的新型材料加工技术，尤其是高级陶瓷。尽管取得了进步，但对材料如何吸收微波的物理理解仍不清楚。研究人员将对先进陶瓷材料进行结构表征研究，以确定不同频率区域的电学/介电性能，重点是高频测量。他们打算将表征扩展到磁性材料和金属粉末。该结果有望揭示微波处理过程中微波吸附的物理机制。这是加工技术中一个快速发展的领域。Agrawal教授是该领域的世界领导者，他在微波表征技术方面有几项创新。宾夕法尼亚州立大学的材料研究实验室是研究先进材料的一流实验室。长期以来，印度研究人员一直致力于研究高频区域材料的电学特性。该项目为宾夕法尼亚州立大学和印度理工学院之间的国际合作和加强机构联系提供了机会。该项目由国际项目司和印度政府科技部联合支持。

The US investigators are Dinesh Agrawal and Michael Lanagan, Pennsylania State University; Indian investigators are Dinesh Dube and H.C. Gupta, Indian Institute of Technology, New Delhi. Microwave processing is emerging as a widely accepted new processing technology for a variety of materials, especially advanced ceramics. In spite of advancements, the physical understanding of how materials absorb microwaves is not understood. The investigators will conduct structural characterization studies on advanced ceramic materials to determine the electrical/dielectric properties in different frequency regions with emphasis on high frequency measurements. They intend to extend characterization to magnetic materials and to metal powders. The results are expected to shed light on the physical mechanisms responsible for microwave adsorption during microwave processing. This is a fast emerging area in processing technology. Scope: Professor Agrawal is a world leader in this area with several innovations in microwave characterization technique to his credit. The Materials Research Laboratory at Penn State University is a premier laboratory for advanced materials. The Indian researchers have long been engaged in investigating electrical properties of materials in the high frequency region. This project offers the opportunity for international collaboration and the strengthening of institutional connections between Penn State and the Indian Institute of Technology, Delhi. The project is jointly supported by the Division of International Programs and the Government of India's Department of Science & Technology.
