title: One dimensional chemical signal diode constructed with two nonexcitable barriers.
abstract: Excitable chemical systems can process information coded in excitation pulses. Here we demonstrate the simplest realization of a chemical signal diode that transmits pulses in one direction only. It is constructed with only two different nonexcitable barriers. The proposed diode has been tested in numerical simulations and in experiments with Ru-catalyzed Belousov-Zhabotinsky reaction.
