The possibility of metamaterials and their basic design principles were introduced 50 years ago by the Russian scientist\, V.G. Veselago\, in his 1968 paper. After a silent period of ab out 30 years\, the research on the theory and applications of metamaterial s became very popular in physics\, electrical engineering and material sci ence with a huge number of publications exceeding 10.000 papers annually. Magnetically and/or electrically excited metamaterial unit cell arrays wer e firstly demonstrated in microwave frequencies\, in early 2000’s. Then\ , the MTM research studies have been extended to Terahertz (THz) and infra red (IR) bands over the last decade. Since 2007\, I have been doing resear ch at METU with my graduate students on the design and applications of met amaterials\, having completed 3 Master Theses and 3 PhD Theses so far\, re sulting in 15 journal papers and more than 30 conference papers. In my pre sentation\, I will summarize our results in metamaterial research reportin g multi- frequency or wideband MTM structures\, including adjustable or re configurable topologies\, with various applications ranging from resonator s\, filters\, antennas and absorbers to sensors in RF\, THz and IR bands.\ n\nBio: Dr. Gönül Turhan-Sayan received her B.S. and M.S. degrees from t he Middle East Technical University (METU)\, Ankara\, Turkey\, and her Ph. D. degree from the Ohio State University (OSU)\, Columbus\, Ohio\, USA\, a ll in electrical engineering. During her PhD studies\, she was a Fulbright Scholar from 1983 to 1984. Then\, she worked for the ElectroScience Labor atory at OSU as a graduate research associate from 1984 to 1988. Dr. Turha n-Sayan was a consultant and subcontractor for the Electromagnetics and Op tics Divisions of the Battelle Memorial Institute\, Columbus\, Ohio\, USA from 1988 to 1992. She joined METU in 1992 as an assistant professor and b ecame a full professor in 2003. She served as the Chairperson of the Depar tment of Electrical and Electronics Engineering from 2013 to 2016\, and as the Vice President of METU from 2016 to August\, 2017. Her professional i nterests include transient electromagnetics\; target detection and physics -based identification techniques for ultra-wideband (UWB) radar systems\; mine and IED (Improvised Explosive Devices) detection by GPRs\; UWB radar signal processing\; design and applications of metamaterials in microwave\ , Terahertz and infrared bands\; distributed fiber optical sensors and opt ical surface plasmon resonance sensors.
