Implementation of Dielectric Metamaterials with Integrated Resonance Response

这项研究的目的是探索新型的全介质超材料，它可以由于共振夹杂物之间的相互作用而提供集成的共振响应。方法是将理论研究、多元素阵列的计算全波建模、设计各种材料结构和原型相结合。智能优点：折射率为负的超材料的性能主要是用均匀化理论来分析的，该理论没有考虑谐振场超出谐振器边界的传播以及由于共振场重叠而导致的多个共振响应的积分所造成的影响。该项目旨在揭示合作共振现象的贡献和潜力，并开发出替代现有超材料的有利的全介质替代材料。集成不同学科的知识，使用强大的模拟工具，以及对材料集成最新成果的认可，将使人们深入了解具有集成共振的工程结构中波过程的本质，增进对折射、遮盖和波限制效应的理解，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、微波和光子设备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。将通过将新知识纳入跨学科课程以及出版物和在国家和国际会议上的发言，包括新组织的讲习班--妇女在电磁学中的作用，来传播新知识。

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.?
