Additive Manufacturing for RF and Microwave Applications
IEEE AP-S
There is growing need to adopt additive manufacturing 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 research directed at developing RF subsystems based on additive technologies. Mainly, the development of a novel ferroelectric nano-ink for printing electrostatically-tunable dielectrics on flexible substrates using direct-ink writing methodologies such as inkjet printing, Aerosol Jet printing, and micro-pen dispensing techniques, will be described. This allows for realizing all-printed high-frequency voltage variable capacitors (varactors) on plastic films to be used in tunable RF and microwave applications such as phased array antennas, conformal antennas, and tunable frequency selective surfaces. Whereas the development and application of such composites are reported in the past, they tend to lack the fundamental tunability property linked to the voltage variability, especially at microwave frequencies. Since there are no previously reported methods to characterize the properties of direct-ink printed dielectrics in the microwave regime, unique RF measurement techniques were developed. These printed varactors were employed in a metamaterial-inspired miniaturized-element Frequency Selective Surfaces (FSS) to realize all-printed frequency-agile FSS structures. Moreover, printed varactors can be utilized to create all-printed tunable phase shifters to be used in fully printed conformal antennas, namely phased array antennas.
The RURI academic-corporate partnership is focused on development of printed devices and subsystems including phased array antennas (2D and 3D), tunable frequency selective surfaces (FSS) and printed varactors. Important elements of the research include hybrid chip integration and additive microelectronic packaging. The newly-formed Printed Electronics Research Collaborative (PERC) will also be described. PERC was created to expand corporate partners to include companies developing the PE supply chain in critical areas such as design tools, materials, equipment, and components. These RF-PE projects are enabled as a result of building an integrated facility at UMass Lowell that includes all phases of PE design (electromagnetic, structural and thermal), printing technologies, material development and characterization techniques.

Biography:
Alkim Akyurtlu received the B.S. degree in electrical engineering from the Virginia Tech, Blacksburg, in 1994, and the M.S. and Ph.D. degrees in electrical engineering from The Pennsylvania State University (Penn State), University Park, PA, 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 design and application of metamaterials and printed electronics for RF and Microwave applications including antennas and novel electromagnetic filters. Her funding resources include the Air Force, NSF, DARPA, ONR, Raytheon, and NASA.
Prior to coming to UML, Dr. Akyurtlu worked at MIT Lincoln Laboratory with the Systems and Analysis Group as a Technical Specialist conducting research on electromagnetic modeling and statistical analysis of radar systems. She was a Summer Faculty Fellow at the Air Force Research Laboratory, Hanscom Air Force Base, MA, in the summer of 2004 and at the NASA Langley Research Center in the summer of 2003, where she received the Best Faculty Fellow Paper Award. She was awarded the Outstanding Teaching Award in the Electrical Engineering Department for the 2002-2003 and the 2010-2011 academic years at UML. Dr. Akyurtlu was an Academic Computing Fellow at Penn State. She was a recipient of the Best Student Paper Award at the 2000 Applied Computational Electromagnetics Society Symposium. 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.
