This book presents the developments and potential applications of Meta-Smith charts, which can be applied to practical and useful transmission line problems (e.g., metamaterial transmission lines and nonreciprocal transmission lines). These problems are beyond the capability of the standard Smith chart to be applied effectively. As any RF engineer is aware, a key property of the Smith chart is the insight it provides, even in very complex design processes. Like the Smith chart, Meta-Smith charts provide a useful way of visualizing transmission line phenomena. They provide useful physical insight, and they can also assist in solving related problems effectively. This book can be used as a companion guide in studying Microwave Engineering for senior undergraduate students as well as for graduate students. It is also recommended for researchers in the RF community, especially those working with periodic transmission line structures and metamaterial transmission lines. Problems are also provided at the end of each chapter for readers to gain a better understanding of material presented in this book.Table of Contents: Essential Transmission Line Theory / Theory of CCITLs / Theory of BCITLs / Meta-Smith Charts for CCITLs and BCITLs / Applications of Meta-Smith Charts

About the author
Danai Torrungrueng received his B.Eng. degree in electrical engineering from Chulalongkorn University, Bangkok, Thailand, in 1993. He obtained his M.S. and Ph.D. degrees in electrical engineering from The Ohio State University in 1996 and 2000, respectively. From 1995 to 2000, he was a Graduate Research Assistant (GRA) in the Department of Electrical Engineering, ElectroScience Laboratory of The Ohio State University. Prior to joining Asian University, he worked as a senior engineer in the USA, involved in research and development of the urban propagation modeling project. At present, he is an associate professor in the Electrical and Electronic Engineering Department in the Faculty of Engineering and Technology at Asian University, Thai[1]land. In 2000, he won an award in the National URSI Student Paper competition at the 2000 National Radio Science Meeting in Boulder, Colorado. During 2004 to 2009, he invented and developed Meta-Smith charts (visit http://www.meta-smithcharts.org) for solving problems associated with conjugately characteristic-impedance transmission lines (CCITLs) and bicharacteristic-impedance transmission lines (BCITLs) graphically. His research interests are in the areas of fast computational electromagnetics, antenna design, RFID, rough surface scattering, prop[1]agation modeling and electromagnetic wave theory. He is currently a senior member of the IEEE and a member of the Electrical Engineering/Electronics, Computer, Telecommunications and In[1]formation Technology Association of Thailand (ECTI).
