This lecture is about mathematics of waves. Waves in structured solids may have interesting and unusual properties. A bridge, for example, can be viewed as a waveguide, and waves can be controlled, so that vibrations are suppressed.

Waves can also be routed around objects by special coatings, invisibility cloaks’’. The lecture explains the theory standing behind these interesting phenomena and includes practical examples. Cloaking is explained via a coordinate transformation applied to the wave equation. Implementations of cloaks are also shown.
