A strong modulation of the resonance frequencies and the gaps of edge magnetoplamons (EMPs), in the ribbon at the ν = 2 quantum Hall effect regime with a superlattice and a smooth steplike electrostatic lateral potential, due to a modulation of the interedge distance is shown. We obtain that, in a wide range of the interedge distances, within THz region the EMPs show wide frequency gaps and at peculiar frequencies the response of the system should manifest resonances. For the latter frequencies the group velocities are nullified
