项目摘要

Multiferroic materials allow for dielectric and magnetic property control through active biasing. Leveraging these features, this project will introduce new types of adaptable and reconfigurable electromagnetic structures. Specifically, the project will develop multiferroic substrates, tunable biasing networks, and electromagnetic structures for packaging and integration on a common platform. Research will also focus on synthesis of multiferroic substrates compatible for such integration. The goal is to attain active control and reconfigurability of bulk substrate properties to provide an adaptable RF shielding of wireless communication systems. Overall, the project aims to increase security to RF systems through mitigation of wireless interferences, concurrently allowing secure data-channels. Focus will be on achieving selective blocking or transmission of radio waves, and reconfigurability of frequency and transmitting direction. This multidisciplinary project will bridge the gap between broadly applicable fields of multiferroics and electromagnetics. The project leverages two active NSF Research Experience for Undergraduates (REU) sites at Florida International University to improve outreach and training of undergraduates.Specifically, the project will introduce new architectures and external magnetic-field biasing to control the dielectric properties of bulk substrates. Material integration will be pursued for tunable reflecting antenna arrays, transmitting antenna arrays, frequency selective surfaces (FSS) and antennas and thus exploit the properties of multiferroic substrates towards tunability. The project has three broad research components: (1) synthesis of multiferroic substrates by embedding core-shell nanoparticles formed by cobalt ferrite cores and barium strontium titanate (BST) shells; (2) integration of frequency selective surfaces and antenna structures, co-designed with tunable multiferroic substrates for dynamic passbands; (3) development of active biasing networks to control multiferroic media properties while concurrently being neutral to the FSS and antenna performance. Beyond these, the project will focus on reducing power levels of active networks for efficient performances. This will be achieved by using nanomagnetic field amplifying agents and multiferroic nanocomposites. Research will also focus on effective packaging of the biasing architectures, electromagnetic structures and multiferroic substrates to achieve 3D excitation and tuning. These solutions will be experimentally demonstrated for tunable shielding applications and subsequently tested with wireless communication systems to demonstrate the project outcomes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

多铁性材料允许通过主动偏置控制介电和磁性特性。利用这些特征，该项目将引入新型适应性和可重构电磁结构。具体来说，该项目将开发多铁基板、可调偏置网络和电磁结构，用于在通用平台上进行封装和集成。研究还将集中于与这种集成兼容的多铁基底的合成。目标是实现体基板特性的主动控制和可重构性，从而为无线通信系统提供适应性强的射频屏蔽。总体而言，该项目旨在通过减轻无线干扰来提高射频系统的安全性，同时允许安全的数据通道。重点将是实现无线电波的选择性阻塞或传输，以及频率和传输方向的可重构性。这个多学科项目将弥合多铁性和电磁学广泛应用领域之间的差距。该项目利用佛罗里达国际大学两个活跃的 NSF 本科生研究经验 (REU) 来改善本科生的推广和培训。具体来说，该项目将引入新的架构和外部磁场偏置来控制块状基板的介电性能。可调谐反射天线阵列、发射天线阵列、频率选择表面（FSS）和天线将寻求材料集成，从而利用多铁基体的特性实现可调谐。该项目分为三大研究组成部分：（1）通过嵌入由钴铁氧体核和钛酸锶钡（BST）壳形成的核壳纳米颗粒来合成多铁性基底；（2）频率选择表面和天线结构的集成，与动态通带的可调谐多铁基板共同设计； (3) 开发有源偏置网络来控制多铁介质特性，同时对 FSS 和天线性能保持中性。除此之外，该项目还将重点关注降低有源网络的功率水平以实现高效性能。这将通过使用纳米磁场放大器和多铁纳米复合材料来实现。研究还将重点关注偏置架构、电磁结构和多铁基板的有效封装，以实现 3D 激励和调谐。这些解决方案将针对可调屏蔽应用进行实验演示，并随后使用无线通信系统进行测试，以展示项目成果。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
