Abstract

In the present article, we simulate the propagation of binary signals in semi-infinite, mechanical chains of coupled oscillators harmonically driven at the end, by making use of the recently discovered process of nonlinear supratransmission. Our numerical results ---which are based on a brand-new computational technique with energy-invariant properties--- show an efficient and reliable transmission of information.
