It is shown that ripple structures on oblique incidence ion bombarded surfaces can be stable features under ion erosion without the necessity to invoke mass redistribution, surface diffusion or micro-roughening due to surface curvature dependent energy deposition. Instead the patterns are predicted to be a natural consequence of non-linear effects due to the dependence of the sputtering yield on the angle of incidence.
