Title: Additive Manufacturing for RF and Microwave Devices
Date: October 27, 2020
Time: 11:00am PT / 2:00pm ET
Presented by: Professors Alkim Akyurtlu and Craig Armiento, University of Massachusetts, Lowell
There is growing need to adopt additive technologies for the production of RF/microwave electronics. This trend is motivated by the need for rapid prototyping and the production of RF systems that are flexible, lightweight, conformable and wearable. Printing RF electronics for DoD applications (e.g., radars, communication systems) is challenging since the requisite materials, components and systems demand higher performance than required for low frequency applications.
This talk will describe several printed devices and subsystems, including tunable frequency selective surfaces, phased arrays, printed phase shifters, and printed varactors. Ink development, hybrid chip integration, printed interconnects, and additive microelectronic packaging are key elements of this research. Our work includes multi-physics based design and modeling as well as the development of printing/processing technologies. The formulation of new materials (inks etc...), and characterization of their properties at microwave frequencies, are key challenges in applying additive manufacturing to printed RF and microwave devices. Details of these challenges and ways of mitigating them through specific applications, which exemplify all stages of development, will be presented. Details of a novel ferroelectric ink, tunable substrates, printed interconnects, and novel ink characterization methods, the key enablers for these applications and devices, will be described.
Alkim Akyurtlu received the B.S. degree in electrical engineering from Virginia Tech in 1994, and the M.S. and Ph.D. degrees in electrical engineering from Penn State in 1996 and 2001, respectively. In 2002, she joined the Department of Electrical and Computer Engineering at University of Massachusetts Lowell (UML), Lowell, MA, where she is a Full Professor. She is also the Deputy Director of the Printed Electronics Research Collaborative (PERC) and Co-Director of the Center for Photonics, Electromagnetics and Nanoelectronics (CPEN). Her research interests are in metamaterials; computational electromagnetics; and printed electronics for RF and Microwave applications including antennas and novel electromagnetic devices. Her funding resources include the Air Force, NSF, DARPA, ONR, Raytheon, and NASA. Prof. Akyurtlu is a member of Tau Beta Pi, IEEE Antennas and Propagation Societies, and has been an Editor for the IEEE Antennas and Transactions Magazine. She is a Senior Member of IEEE.
Craig Armiento is the Co-Director of the Raytheon UMass Lowell Research Institute (RURI) and the Director of the Printed Electronics Research Collaborative (PERC). He served as ECE Department Chair from 2005-2011. Prior to coming to UMass Lowell in 2003, Prof. Armiento had over twenty years of industrial R&D experience. He led research projects at GTE Laboratories (now Verizon) on projects including Fiber-to-the-Home (now FiOS), optoelectronic hybrid integration, III-V device fabrication, GaAs ICs, semiconductor lasers and avalanche photodiodes. He also was Director of Optical Networking at Lightchip Optical Networks Inc. and was a researcher at M.I.T. Lincoln laboratory. Prof. Armiento has over 100 publications and presentations and 18 U.S. patents. His Ph.D. and M.S. degrees are from M.I.T. and his B.S.E.E. is from Manhattan College.
