INT 9811609 Davies这个美国-斯洛文尼亚的一项研究项目涉及宾夕法尼亚大学的彼得·戴维斯和卢布尔雅那大学约瑟夫·斯特凡研究所的达尼洛苏沃罗夫，他们检查了一组微波介电陶瓷。 合作将包括一系列步骤，包括新粉末组合物的制备、晶体化学和结构，以及陶瓷材料的加工和介电特性。 结果应该产生一个详细的分析候选氧化物，包括烧绿石和钙钛矿相关的晶体结构的系统的微波响应。其目的是1）提高我们对成功的陶瓷谐振器的关键化学和结构要求的理解，2）确定微波材料开发的新领域，其中存在创造具有更高介电常数和更低介电损耗的新型陶瓷的潜力。 如果成功的话，这种材料可能适用于微波通信技术。该材料研究项目实现了通过使美国和中欧的领先专家在相互感兴趣和能力强的领域联合收割机互补人才和集中研究资源来推进科学知识的计划目标。 ***

INT 9811609DaviesThis U.S.-Slovene research project involving Peter Davies of the University of Pennsylvania and Danilo Suvorov of the Josef Stefan Institute, University of Ljubljana, examines a set of microwave dielectric ceramics. Collaborative efforts will feature a range of steps including preparation, crystal chemistry and structure of new powder compositions as well as processing and dielectric characterization of the ceramic materials. Results should produce a detailed analysis of the microwave response for candidate oxides that include systems with pyrochlore and perovskite related crystal structures. The intent is to 1) improve our understanding of the critical chemical and structural requirements for a successful ceramic resonator and 2) identify new areas for microwave materials development where potential exists for creating novel ceramics with higher dielectric constants and lower dielectric losses. If successful, such materials may have applicability in microwave-based communication technologies.This materials research project fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Central Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ***
