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.
