Microwave Applications of Metamaterial Structures

"Microwave Applications of Metamaterial Structures"Tatsuo ItohUniversity of California, Los AngelesMetamaterials are artificial or man-made structures that have properties not found in naturally existing materials. The most unusual metamaterials are the Left-Handed ones, also called Double Negative or Negative Refractive Index materials, which are characterized by simultaneously negative permittivity and permeability. Many interesting EM propagation phenomena result from the negativeness of the constitutive parameters. For instance, the phase and the group velocities are anti-parallel in a Left-Handed substance. Fundamental theoretical research as well as research on possible revolutionary applications for microwave and RF circuits is underway at various organizations. Although the technology is still in its infancy, novel practical developments have already been proposed. The talk will contain a brief historical account, fundamental concepts, adaptation to microwave environment and emerging applications for antennas, passive components and active circuits with unique features at microwave frequencies.Tatsuo Itoh received the Ph.D. Degree in Electrical Engineering from the University of Illinois, Urbana in 1969. He worked at University of Illinois, SRI, University of Kentucky, AEG Telefunken in Germany and The University of Texas at Austin. In January 1991, he joined the UCLA as Professor of Electrical Engineering and holder of the TRW Endowed Chair in Microwave and Millimeter Wave Electronics. He has visiting appointment with University of Leeds, UK. Dr. Itoh is a Fellow of the IEEE, served as the Editor of IEEE Transactions on Microwave Theory and Techniques for 1983-1985, was President of the MTT Society in 1990 and was a founding Editor-in-Chief of IEEE Microwave and Guided Wave Letters from 1991 through 1994. He was elected as an Honorary Life Member of MTT Society in 1994. He was the Chairman of Commission D of the URSI for 1993-1996. He received a number of awards including Shida Award from Ministry of Post and Telecommunications, Japan and Japan Microwave Prize, IEEE Third Millennium Medal and IEEE MTT Distinguished Educator Award. He is a member of National Academy of Engineering. He was Distinguished Microwave Lecturer for IEEE MTT Society on Microwave Applications of Metamaterial Structures for 2004 - 06. He has over 1000 publications and generated 66 Ph.D's in the area of microwave and millimeter-waves, computational electromagnetics, antennas, microwave photonics.EBG and Negative Index Materials.
