Metamaterials are artificial, engineered materials designed to manipulate wave propagation in ways not possible with conventional materials. An Introduction to Waves in Mechanical Periodic Structures and Metamaterials presents a systematic and rigorous treatment of wave propagation in periodic structures, with a particular focus on mechanical and acoustic metamaterials. The book bridges fundamental concepts and advanced topics, offering a unified framework to analyze discrete and continuous periodic systems. Key topics include:

• Comprehensive mathematical formulation of wave propagation in solids and periodic structures
• In-depth discussion on bandgap formation through Bragg scattering, local resonance, and inertial amplification
• Coverage of advanced concepts such as meta-damping, non-reciprocity, active control, and nonlinear metamaterials
• Unique focus on damping evaluation in metamaterials, critical for shock resistance and transient dynamic applications

This book serves as an accessible yet rigorous resource for senior undergraduate and graduate students in structural engineering, mechanical engineering, applied physics, and materials science, as well as for researchers seeking to deepen their understanding of wave mechanics in metamaterials.
