小行星9622326托马斯 这个项目是一个合作的努力，将涉及机械和电气工程师和材料科学家从一所大学，一个联邦实验室，和两个制造公司。 该研究将开发技术，探索微波腔设计，微波加热模式，以及与热失控材料连续加工有关的电磁和热测量和控制。 热失控材料是当暴露于微波场时，介电损耗因子随着其温度升高而更快地增加的那些材料。 在加工过程中无法控制温度，这阻碍了微波加工在许多商业上重要的材料中的广泛应用。 微波加热为以较低的成本生产出更好的产品提供了可能，提高了美国食品工业的国际竞争力。S.纤维和化学工业。 这项研究的结果可能适用于广泛的材料，特别是那些由聚合物和陶瓷制成的材料。

9622326 Thomas This project is a collaborative effort that will involve mechanical and electrical engineers and materials scientists from a university, a federal laboratory, and two manufacturing companies. The research will develop techniques to explore microwave cavity design, microwave heating patterns, and electromagnetic and thermal measurements and control pertaining to continuous processing of thermal runaway materials. Thermal runaway materials are those in which dielectric loss factors increase more rapidly as their temperature rises when exposed to a microwave field. The inability to control temperatures during processing prevents widespread use of microwave processing for many commercially important materials. Microwave heating offers the possibility for better products at lower cost, increasing the international competitiveness of U. S. fiber and chemical industries. Results of this research may be applicable to a wide range of materials, especially those made from polymers and ceramics.
