(color online) The input electrons are taken to have s = ↑ in all cases. Spin conductance as a function of kl when a chain of hexagonal rings is connected at the nodes for (a) m = 3 and (b) m = 4. Spin conductance as a function of kl when a chain of octagonal rings is connected at nodes for (c) m = 3 and (d) m = 4. In all cases, the strength of the DSOC is α_D = 0.05π.
