Metamaterials have transformed the study and control of waves, enabling effects such as negative refraction, cloaking, tailored dispersion, and programmable wavefront shaping. The field has expanded quickly from its electromagnetic origins into acoustics, elasticity, and time-varying platforms, creating a need for an introductory text that links core physical ideas with modern developments in a clear and gradual way. This book is written for advanced undergraduates and first-year postgraduate students who are starting research or looking for a structured entry point into the area.

Key Features:

• Background theory with full mathematical details
• Classical and important examples
• Practical guide to start in the research area
• Coherent and self-contained, for wide audience with minimal background
• Up-to-date coverage of development of the field
