Porous alumina arrays with various Moiré patterns (see Figure) are prepared by two-step nanoindentation with different rotation angles and subsequent anodization. The patterns on the porous alumina array are in good agreement with the theory of Moiré patterns in terms of the rotation angles. In addition, replicas of photoresist polymer with the Moiré pattern are successfully prepared.
