In living organisms, signals propagate through various kinds of geometrical or boundary paths. It is well established that a traveling wave can be generated on an excitable field; this generation is described by reaction-diffusion equations for an activator and inhibitor. I use a numerical simulation to show that the signaling pulse can be transmitted from an excitable field to an opposing excitable field via an intervening passive diffusion field in a characteristic manner that depends upon the spatial geometry of the excitable fields. Using such characteristics, it is possible to design various kinds of simple information operations.
