We present the one‐electron spectrum and eigenstates of bounded graphene nanoribbons that describe electron dynamics in terms of transverse and longitudinal motion. On this basis, we find the transmission coefficients for armchair graphene nanoribbons and polyacene under step‐like electronic potential. The problem is solved for different interfaces between the regions with zero and nonzero site energies. The obtained results have numerous applications to the construction of multi‐terminal graphene‐based electronic devices.
