ON THE GENERATION OF LOCALIZED NONLINEAR MODES IN A LINEAR ARRAY OF ANHARMONIC OSCILLATORS
In this work, we show that an adequate modulation of the driving amplitude in an anharmonic chain results in an efficient transmission of binary information. The nonlinear processes of supratransmission and infratransmission are shown to be useful in the solution of the problem under investigation. Numerical results are conducted using a finite-difference scheme with consistency properties in the energy domain, and the experiments show that localized nonlinear modes are propagated through the chain in a reliable and controlled manner.
