Summary:
A macro-mechanical cantilever array is newly proposed for experimental investigations of intrinsic localized modes (ILMs). The cantilever array is designed to have individually tunable on-site potentials. Thus, impurities in the array can be induced and removed manually. By a sinusoidal excitation, several ILMs are successfully generated. In addition, the generated ILM is manipulated by adding an impurity to the cantilever array. The mechanism of the manipulation is numerically discussed based on the structure of phase space. Coexisting ILMs, unstable manifolds, and domains of attraction of stable ILM are shown for the case that an ILM is manipulated by adding an impurity.
