TY  - JOUR
AB  - We report the formation of “ripple” patterns by the sequential superposition of nonorthogonal surfacewaves excited by the spontaneous buckling of polymeric bilayers. Albeit of a different nature and micronscale compared to the familiar sedimentary ripples caused by gentle wave oscillations, we findcommonalities in their topography, defects, and bifurcations. The patterns are rationalized in terms ofa defect density that depends on the relative angle between generations, and a constant in-plane bendingangle that depends on skin thickness. A minimal wave summation model enables the design of ripple andcheckerboard surfaces by tuning material properties and fabrication process.
