This third edition builds on the introduction of spectral analysis as a means of investigating wave propagation and transient oscillations in structures. Each chapter of the textbook has been revised, updated and augmented with new material, such as a modified treatment of the curved plate and cylinder problem that yields a relatively simple but accurate spectral analysis. Finite element methods are now integrated into the spectral analyses to gain further insights into the high-frequency problems. In addition, a completely new chapter has been added that deals with waves in periodic and discretized structures. Examples for phononic materials meta-materials as well as genuine atomic systems are given.

Systematically develops and then applies the spectral methods to analyzing the dynamic responses Examines spectral analysis of discrete and discretized structures Explains spectral analysis as applied to metamaterials and nanostructures Reinforces reader understanding with a combination of experimental and analytical results related to wave propagation in structures
