Patterns of traveling intrinsic localized modes in a driven electrical lattice.

Received 1 February 2008; published 2 June 2008The emergence of very stable traveling intrinsic localized modes ILMs locked to a uniform driver isdemonstrated in a discrete electrical transmission line. The speed of these traveling ILMs is tunable by thedriver amplitude and frequency. It is found to be quite sensitive to the ratio of intersite to on-site nonlinearity.The number of traveling ILMs can also be selected via the driving conditions and appears to be the result ofa spatiotemporal pattern selection process.DOI: 10.1103/PhysRevE.77.066601 PACS number s : 05.45.Yv, 63.20.Pw, 47.54.De
