We show that magnetic nonlinear response in such microstructured composites can be enhanced significantly compared to bulk media, since the local electric fields in metallic microresonators may become extremely strong. We predict that engineering nonlinear properties of metamaterials may allow for various applications, including a dynamic control and tunability of the electromagnetic properties of the composite structures, second-harmonic generation, intensity-dependent switches, and even soliton generation. We present our results on the experimental observation of nonlinear effects in arrays of tunable split-ring resonators for microwaves and discuss possible ways for the future developments of nonlinear tunable metamaterials.
