Zero Index Metamaterials : Trends and Applications This book presents the emerging regime of zero refractive index photonics involving metamaterials that exhibit effectively zero refractive index. Metamaterials are artificial structures whose optical properties can be tailored at will. With metamaterials intriguing and spellbinding phenomena like negative refraction and electromagnetic cloaking could be realized which otherwise seem unnatural or straight out of science fiction. Zero index metamaterials are also seen as a means of boosting nonlinear properties and are believed to have strong prospects for being useful in nonlinear optical applications. In summary this book highlights almost everything currently available on zero index metamaterials and is useful for professionally interested and motivated readers. Electromagnetics for zero index metamaterials Zero index metamaterials Applications of zero index metamaterials Nonlinear optics with zero index metamaterials Recent advances in zero index photonics.
