A nonlinear electromagnetic field (energy) concentrator is considered and the new method of nonlinear transformational optics is developed. This method includes two connected techniques: the complex geometrical optics (CGO) and the full‐wave nonlinear solution. A possibility of the strong “nonlinear superfocusing” of a field in a small volume is predicted theoretically and a tendency to formation of “hot spot(s)” is shown. The proposed method of nonlinear energy concentration may be perspective for solar cells, subwavelength imaging, high harmonic generation etc.
