Metamaterials

A Convincing and Controversial Alternative Explanation ofMetamaterials with a Negative Index of Refraction In a book that will generate both support and controversy, oneof the world's foremost authorities on periodic structuresaddresses several of the current fashions in antennadesign--most specifically, the popular subject of doublenegative metamaterials. Professor Munk provides a comprehensivetheoretical electromagnetic investigation of the issues andconcludes that many of the phenomena claimed by researchers may beimpossible. While denying the existence of negative refraction, theauthor provides convincing alternative explanations for some of theexperimental examples in the literature. Although the debate on this subject is just beginning, ProfessorMunk has received support by various numerical simulations, winninghim the encouragement of numerous experts in the field. The issuesthat are raised here have not been addressed thoroughly by themetamaterials community, and this book will serve as a catalyst formuch healthy debate and discussion. Metamaterials: Critique and Alternatives is destined tobecome a classic resource for graduate students and researchers inelectromagnetics, antenna theory, materials research, andchemistry.
