Metamaterials: Critique and Alternatives

Metamaterials are a new class of ordered composites that exhibit exceptional properties not readily observed in nature. In Metamaterials, Professor Munk, a leading expert on periodic structures, denies the existence of negative refraction and provides convincing alternative explanations involving surface waves to some of the experimental examples of metamaterials in the literature. While the debate on this subject is just starting, Professor Munk's arguments should be the catalyst to much healthy discussion amongst researchers and graduate students in electromagnetics, antenna theory, materials research, and chemistry.
