报告人:Dr. Naumenko
      The presentation starts from the short overview of SAW devices, including the main landmarks in the development of SAW devices, from invention of interdigital transducer to high-performance SAW resonators for communication systems and sensors. Special attention will be paid to design of SAW resonators: the main steps of design process, numerical and half-analytical techniques most widely used for simulation of SAW resonators will be overviewed. The talk will continue with main tendencies in SAW resonator design today, such as advanced simulation of different physical effects and application of multi-layered structures to improve SAW resonator performance. The most promising multi-layered structures will be demonstrated with visualization of waves propagating in these structures, for example, SH-waves potentially useful for application in liquid SAW sensors. 
     Dr. Naumenko received Ph.D. degree in the physics of dielectrics and semiconductors from the Moscow Steel and Alloys Institute (Technological University) in 1984. From 1979 to 1990 she worked on SAW device design in the Radio-Engineering Research Institute, Moscow. Since 1990 she is with National University of Science and Technology “MISIS”, Moscow, where she combines research work with teaching activities. From 1995 to 2011, Dr. Naumenko also served as a consultant for the company TriQuint Semiconductors (SAWTEK Inc. before 2001, QORVO today), Apopka, FL. She was engaged in modeling and development of advanced software for improvement of SAW device performance and investigation of new materials for SAW devices. From 2011 to 2014 she performed few research projects in design of resonator SAW filters for TDK-EPCOS, Germany. Since 2014 she investigated new materials for SAW sensors for the company CTR, Austria. 
        Dr. Naumenko is the author of 14 issued U.S. patents and few European patents (all assigned to TriQuint, USA) on the optimal substrate orientations for SAW devices, including the patent on the optimal cut of LGS widely used today in SAW sensors and filters. She has more than 90 publications in SAW material research and different aspects of SAW resonator design. Her current research interests include investigation of materials and development of improved simulation tools for design of SAW and BAW devices, such as resonator SAW filters, delay lines and wireless SAW sensors. Since 2011 Dr. Naumenko is a member of the Technical Program Committee of the IEEE Ultrasonic Symposium. In 2016, she presented a joint course on SAW sensors to attendees of the Ultrasonics Symposium in Tour, France.
