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.

多效材料允许通过主动偏置来控制介电和磁性特性。利用这些功能，该项目将引入新型的适应性和可重新配置的电磁结构。具体而言，该项目将开发多效底物，可调偏见网络和电磁结构，用于在公共平台上包装和集成。研究还将集中于合成这种整合的多效底物。目的是实现散装基材属性的主动控制和可重新配置，以提供无线通信系统的适应性RF屏蔽。总体而言，该项目旨在通过缓解无线干扰来提高RF系统的安全性，同时允许安全的数据通道。重点将放在实现无线电波的选择性阻断或传输上，以及频率和传输方向的可重新配置性。这个多学科的项目将弥合多效学和电磁学领域的广泛适用领域之间的差距。该项目利用佛罗里达国际大学的本科生（REU）的两种活跃的NSF研究经验来改善本科生的外展和培训。特别是，该项目将引入新的建筑和外部磁场偏见，以控制散装基质的介质特性。对于反射天线阵列，传输天线阵列，频率选择性表面（FSS）和天线的可调式可调节，将追求材料的整合，从而利用了多效底物的性能降低了可调性。该项目具有三个广泛的研究组成部分：（1）通过嵌入由钴铁氧体核心和钛钛酸钡（BST）壳形成的核壳纳米颗粒来合成多用量底物；（2）集成频率选择性表面和天线结构，并与可调的多效性底物共同设计用于动态通带；（3）开发主动偏置网络以控制多性培养基，同时与FSS和天线性能同时中性。除此之外，该项目还将集中于降低主动网络的功率水平以进行有效的性能。这将通过使用纳米磁场扩增剂和多性纳米复合材料来实现。研究还将集中于有效包装偏见架构，电磁结构和多性底物，以实现3D激发和调整。这些解决方案将在实验中进行可调屏蔽应用，然后通过无线通信系统进行测试，以证明项目成果。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响来通过评估来获得支持的。
