“The book is easy to read, but it is also very specialized, so it is recommended for students, scientists, and engineers in materials, electronics, optics, mechanics, acoustics, telecommunications, or related areas … . I enjoyed reading the book; concepts are explained well, with examples of a wide variety of functional metamaterials and metadevices applications. The audience for this book would be students, professionals, or researchers in the areas of physics, optoelectronic engineering, electronics, mechanics, materials engineering or nanotechnology.” (Miriam Sánchez Pozos,MRS Bulletin, Vol. 44 (2), February, 2019)
