This project focuses on the development of voltage-controlled magnetic materials for low loss microwave devices and circuits, including isolators and circulators which are key components that allow one way signal propagation. A key innovation of this program is the use of an organic-based magnetic material to construct the microwave circuits, much in the same way that organic light-emitting diodes (OLEDs) have allowed new display technologies. This approach leverages existing infrastructure developed for commercial microwave magnetic devices. Given the critical role those devices play in wireless communication and information technology, the breadth and depth of the impact of this work will be significant. Additionally, this research program will form the foundation for broader efforts at increasing public engagement in science via local outreach activities that are designed to enhance diversity programs in STEM across the four participating university campuses (Colorado State University, University of Iowa, Ohio State University, and Yale University). This project focuses on the development of novel approaches to achieving/enhancing non-reciprocity in microwave devices. Specifically, we have defined two parallel and synergistic Tracks that exploit the existing infrastructure surrounding magnetic-based microwave devices as a springboard for the development of novel device architectures based on high-fidelity self-biased magnonic crystals (Track 1) and voltage-control via the Dzyaloshinskii-Moriya interaction (Track 2). In both of these architectures, topologically protected propagating states will be exploited to dramatically enhance non-reciprocity in microwave devices such as circulators, isolators, and non-reciprocal filters. These projects are critically enabled by a recent materials breakthrough in which thin films of a room temperature organic-based magnet have been shown to exhibit magnetic ordering temperatures of over 600 K, quality factors in excess of 8,000 for magnetic resonance, conformal and low temperature deposition, and materials stability under ambient conditions. These projects are individually impactful and collectively synergistic, providing multiple paths to technological advances that will transform the phase space for the design of non-reciprocal microwave devices.

该项目着重于用于低损耗微波设备和电路的电压控制磁性材料的开发，包括隔离器和循环器，这些隔离器和循环器是允许一种方式信号传播的关键组件。该程序的一个关键创新是使用有机的磁性材料来构建微波电路，就像有机发光二极管（OLEDS）允许新的显示技术一样。这种方法利用为商业微波磁性设备开发的现有基础设施。鉴于这些设备在无线通信和信息技术中起着至关重要的作用，因此这项工作影响的广度和深度将非常重要。此外，该研究计划将构成更广泛的努力基础，以通过本地外展活动来增加公众参与科学的参与，这些活动旨在增强四个参与大学校园的STEM（科罗拉多州立大学，爱荷华大学，俄亥俄州大学，俄亥俄州立大学和耶鲁大学）。该项目的重点是开发新型方法​​，以实现/增强微波设备中的非收益。具体而言，我们定义了两个平行且协同的轨道，这些轨道利用了围绕磁性微波设备的现有基础架构，作为弹簧板，以通过Dzyaloshinskii-Moriya Interaction（轨道2）（轨道2）开发基于高保真自偏的镁晶体（轨道1）和电压控制的新型设备体系结构。在这两个架构中，拓扑保护的传播状态将被利用，以显着增强微波设备（例如循环器，隔离器和非股发过滤器）中的非循环性。这些项目是通过最近的材料突破来促进这些项目的，在该材料突破中，室温有机磁铁的薄膜已显示出超过600 k的磁性排序温度，磁共振效果超过8,000，用于磁共振，保形和低温沉积，以及在环境条件下材料稳定性。这些项目具有个人影响力和共同的协同作用，为技术进步提供了多种途径，这些途径将改变设计非重点微波设备的相位空间。
