Nanosphere lithography is a known method for creating ordered metallic nanostructures. We present a modification of this inexpensive and varied full technique, which extends the possibilities of creating different morphologies. Computer simulations were used to determine geometric configurations of the metal deposition system for creating various structures. We will show some examples of bimetallic nanosized periodic-oriented large areas of nanostructures. Very good correlations between the predicted simulation and experimental results were achieved. An additional goal was the prevention of magnetic particles from oxidation. Presented arrays of nanostructures have interesting magnetic and optical properties due to complex geometry, different to previously investigated spherical shapes which are obtainable by standard geometric configuration. The possible application will be also discussed.
