Metamaterials are artificial materials and their properties cannot be obtained with natural materials. Metamaterials are a new subject that has been studied especially in the last 20 years. Application and research areas continue to increase and become widespread in many different engineering fields. The aim of this book is to create a reference guide on the wide range of uses of metamaterials for experts working in sectors such as physics, electromagnetics, electrodynamics, acoustics, microwaves and antennas, as well as researchers working in fields such as physics, electrical and electronics, and aviation.

The scope of the book includes the characterization of metamaterials and structures with metamaterial approaches in the literature, sensor, signal absorber, energy harvesting, frequency selective surface, metasurface, flexible metamaterial and acoustic applications. These applications include microwave, terahertz, optical and acoustic frequency ranges. As it is known that metamaterials are interested in researchers and engineers from many fields of science, the scope of the book has been kept as broad as possible. Sector applications where metamaterials are used are increasing, and it is thought that they will enter our daily lives with important applications in the coming years. For this reason, this book will be an important reference for many applications.
