A Convincing and Controversial Alternative Explanation of
Metamaterials with a Negative Index of Refraction
In a book that will generate both support and controversy, one
of the world's foremost authorities on periodic structures
addresses several of the current fashions in antenna
design--most specifically, the popular subject of double
negative metamaterials. Professor Munk provides a comprehensive
theoretical electromagnetic investigation of the issues and
concludes that many of the phenomena claimed by researchers may be
impossible. While denying the existence of negative refraction, the
author provides convincing alternative explanations for some of the
experimental examples in the literature.
Although the debate on this subject is just beginning, Professor
Munk has received support by various numerical simulations, winning
him the encouragement of numerous experts in the field. The issues
that are raised here have not been addressed thoroughly by the
metamaterials community, and this book will serve as a catalyst for
much healthy debate and discussion.
Metamaterials: Critique and Alternatives is destined to
become a classic resource for graduate students and researchers in
electromagnetics, antenna theory, materials research, and
chemistry.
