We introduce synchronous and nonsynchronous modes in vibration systems, and the use of complex modes for describing nonsynchronous motions, for example traveling waves.  We then briefly review proper orthogonal decomposition (POD), which is a common tool for the extraction of real “energy modes” in spatiotemporal systems.  Some generalizations of POD that enable extractions of complex modes are then presented.  Illustrative examples of these tools shown, including the application of a state-variable modal decomposition to an end-damped beam, and the application of complex orthogonal decomposition to structures and bio-locomotion.
