We study chaotic properties of eigenstates for periodic quasi‐1D waveguides with “regular” and “random” surfaces. Main attention is paid to the role of the so‐called “gradient scattering” which is due to large gradients in the scattering walls. We demonstrate numerically and explain theoretically that the gradient scattering can be quite strong even if the amplitude of scattering profiles is very small in comparison with the width of waveguides.
