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.
