Definitions
Wave propagation in microstructured materials is discussed, and the general framework of wave propagation in generalized continua is described. The principal features of most common generalized models are considered. A basic toolbox for studying wave propagation in generalized continua is provided.
Introduction
The study of elastic waves is a topic that always gathered the interest of the scientific community. From the point of view of applications, elastic waves are currently used in nondestructive evaluation, characterization, and diagnostics. More recently, devices based on surface acoustic waves are a common part of integrated circuits in wireless devices. In the last decades, the interest grew in studying materials with exotic or uncommon properties (the so-called metamaterials). This recent developments demonstrate the need for more sophisticated modeling techniques and stimulated the revival of generalized...
