NSF ECCS Proposal #0725386Novel Magnetic Nano Films and Devices for Millimeter Wave CommunicationsPrincipal Investigator: Carl E. PattonCo-Principal Investigator: Mingzhong WuThe research objective is to use standing spin wave resonance (SSWR) in magnetic films todevelop a new class of millimeter wave radar and signal processing devices that are compatible withmonolithic integrated circuit technology. The program will use thin films with pinned surface spinsthat support SSWR modes across the film thickness. In very thin films, these modes give a largeeffective exchange field that shifts the corresponding FMR frequencies into the millimeter wave range.The target film materials will include ferrite films and high-magnetization metallic films, as well asmultilayer structures. The films/structures will be produced by pulsed laser deposition, e-beamevaporation, and magnetron sputtering, and integrated into prototype devices such as circulators,isolators, notch filters, bandpass filters, phase shifters, and directional couplers.Intellectual merit: The fabrication of new nano films and structures will advance film depositionscience and technology. The characterization work will advance the understanding of magnetic lossprocesses at millimeter wave frequencies. The device development will advance millimeter wavedevice physics and technology. The new devices will have a major impact in both commercial anddefense technology arenas.Broader impacts: The impact on the fields of nano-materials technology and millimeter wavescience and technology will be substantial. Underrepresented groups will be involved through theColorado State University (CSU) diversity recruitment and retention program and the Army sponsoredsummer Research and Engineering Apprenticeship Program. Experiential learning at the K-12 levelwill be promoted through a partnership with the CSU Little Shop of Physics.

NSF ECCS提案#0725386毫米波通信用新型磁性纳米薄膜和器件首席研究员：Carl E. Patton共同主要研究者：吴明忠研究的目的是利用磁性薄膜中的自旋驻波共振（SSWR）技术，研制出一种与单片集成电路工艺兼容的新型毫米波雷达和信号处理器件.该计划将使用具有固定表面自旋的薄膜，支持整个薄膜厚度的SSWR模式。在非常薄的薄膜中，这些模式提供了一个大的有效交换场，将相应的FMR频率移动到毫米波范围。目标薄膜材料将包括铁氧体薄膜和高磁化金属薄膜，以及多层结构。薄膜/结构将通过脉冲激光沉积，电子束蒸发和磁控溅射生产，并集成到原型设备中，如循环器，隔离器，陷波滤波器，带通滤波器，移相器和定向couplers.Intellectual优点：新的纳米薄膜和结构的制造将推进薄膜沉积科学和技术。表征工作将推进在毫米波频率的磁损耗过程的理解。该器件的发展将推动毫米波器件物理和技术的发展。这些新设备将在商业和国防技术领域产生重大影响。更广泛的影响：对纳米材料技术和毫米波科学技术领域的影响将是巨大的。代表性不足的群体将通过科罗拉多州立大学（CSU）的多样性招聘和保留计划以及陆军赞助的夏季研究和工程学徒计划参与。在K-12水平的体验式学习将通过与CSU物理小商店的伙伴关系促进。
