The objective of this research is to explore novel all-dielectric metamaterials that can provide integrated resonance responses due to interaction between resonating inclusions. The approach is to combine theoretical studies, computational full-wave modeling of multi-element arrays, designing various material architectures, and prototyping. Intellectual Merit: The performance of metamaterials with negative refractive index is mainly analyzed by using homogenization theory, which does not account for the effects caused by resonance field spreading beyond resonator boundaries and integration of multiple resonance responses due to resonance field overlapping. This project aims to reveal the contribution and potential of cooperative resonance phenomena and to develop advantageous all-dielectric alternatives to existing metamaterials. Integration of knowledge from different disciplines, employment of powerful simulation tools, and approbation of the latest achievements in materials integration will provide deep insight into the nature of wave processes in engineered structures with integrated resonances, advance understanding of the refraction, cloaking and wave confinement effects, and uncover unknown metamaterial properties. Broader Impacts: Development of low-loss all-dielectric metamaterials with new functionalities will trigger innovative solutions for radio frequency, microwave, and photonic devices and systems. This work will impact communication, imaging, medical, and homeland security equipment. Expected advances will enrich research and education opportunities for undergraduate and graduate students and will attract students to the complex field of electromagnetics. Dissemination of new knowledge will be provided by its incorporation into interdisciplinary courses and by publications and presentations at national and international conferences including the newly organized workshop ?Women in Electromagnetics.?

本研究的目的是探索一种新型的全介电介质超材料，这种材料可以通过共振包涵体之间的相互作用提供集成的共振响应。方法是结合理论研究、多单元阵列的全波计算建模、设计各种材料架构和原型。智力优势：对负折射率的超材料的性能分析主要采用均质化理论，没有考虑共振场扩展到谐振腔边界以外的影响以及共振场重叠引起的多个共振响应的积分。本项目旨在揭示协同共振现象的贡献和潜力，并开发出具有优势的全介电材料替代现有的超材料。整合不同学科的知识，使用强大的模拟工具，认可材料集成方面的最新成果，将深入了解具有集成共振的工程结构中波过程的本质，推进对折射、遮蔽和波约束效应的理解，并揭示未知的超材料特性。更广泛的影响：具有新功能的低损耗全介质超材料的开发将引发射频、微波和光子器件和系统的创新解决方案。这项工作将影响通信、成像、医疗和国土安全设备。预期的进展将丰富本科生和研究生的研究和教育机会，并将吸引学生进入复杂的电磁学领域。新知识的传播将通过将其纳入跨学科课程以及在包括新组织的讲习班在内的国家和国际会议上发表出版物和演讲来提供。学电磁学的女人？
