Kwon Publishes Book on Transformation Electromagnetics and Metamaterials

Do-Hoon Kwon of the Electrical and Computer Engineering Department has published a book with Springer Publishers entitled Transformation Electromagnetics and Metamaterials: Fundamental Principles and Applications. Kwon edited the book with Douglas H. Werner. The book peovides “a systematic design technique for optical and electromagnetic devices that enables novel wave-material interaction properties.” It describes the recent invention of the transformation electromagnetics design technique, gives a comprehensive treatment of the subject matter from a group of leading scholars and researchers throughout the world, and includes both fundamental theoretical principles and application examples encompassing a wide range of spectra.

Kwon’s research interests are wideband antennas, small antennas, frequency selective surfaces, metamaterials, cloaking, and transformation electromagnetics. He is affiliated with the Antennas and Propagation Laboratory and the Center for Advanced Sensor and Communication Antennas. Kwon earned his B.S. from the Korea Advanced Institute of Science and Technology in 1994 and his M.S. (1995) and Ph.D. (2000) from Ohio State University.

The following is the publisher’s description of the book:

Transformation electromagnetics is a systematic design technique for optical and electromagnetic devices that enables novel wave-material interaction properties. The associated metamaterials technology for designing and realizing optical and electromagnetic devices can control the behavior of light and electromagnetic waves in ways that have not been conventionally possible. The technique is credited with numerous novel device designs, most notably the invisibility cloaks, perfect lenses, and a host of other remarkable devices.

Transformation Electromagnetics and Metamaterials: Fundamental Principles and Applications presents a comprehensive treatment of the rapidly growing area of transformation electromagnetics and related metamaterial technology with contributions on the subject provided by a collection of leading experts from around the world. On the theoretical side, the following questions will be addressed: “Where does transformation electromagnetics come from?,” “What are the general material properties for different classes of coordinate transformations?,” “What are the limitations and challenges of device realizations?,” and “What theoretical tools are available to make the coordinate transformation-based designs more amenable to fabrication using currently available techniques?” The comprehensive theoretical treatment will be complemented by device designs and/or realizations in various frequency regimes and applications including acoustic, radio frequency, terahertz, infrared, and the visible spectrum. The applications encompass invisibility cloaks, gradient-index lenses in the microwave and optical regimes, negative-index superlenses for sub-wavelength resolution focusing, flat lenses that produce highly collimated beams from an embedded antenna or optical source, beam concentrators, polarization rotators and splitters, perfect electromagnetic absorbers, and many others.

This book will serve as the authoritative reference for students and researchers alike to the fast-evolving and exciting research area of transformation electromagnetics/optics, its application to the design of revolutionary new devices, and their associated metamaterial realizations. (2013)
