Asymmetric Wave Transport in Nonlinear System
Deterministic chaos, fractal structures and other beautiful phenomena are manifestations of the nonlinear character of forces which govern our world. Besides a revolutionary change in our approach to predictability, these discoveries had great impact on technological applications. Among the most fascinating ones is the possibility to control energy flows by tuning nonlinear features of complex materials.
In the context of wave propagation trough nonlinear media, the simplest form of control would be to devise a “wave diode” in which electromagnetic or elastic waves are transmitted differently along two opposite propagation directions.… Read the rest
