Design and fabrication of diverse metamaterial structures by holographic lithography

We demonstrate a holographic lithography for the fabrication of diverse metamaterial structures by using an optical prism. Cylindrical nanoshells, U-shaped resonator arrays, and double-split ring arrays are obtained experimentally by real time modulating the phase relation of the interference beams. This easy-to-use method may provide a roadway for the design and fabrication of future metamaterials requiring diverse structures for effectively manipulating electromagnetic properties at optical frequencies.
