Multiple-beam surface plasmon holographic nanolithography based on a hemispherical prism coupling configuration is numerically studied in this paper. The proposed configuration is systematically analyzed and optimized for the purpose of achieving five different two-dimensional Bravais lattices by means of adjusting the spatial distribution of three incident beams properly. Furthermore, it is shown that the variation in the relative phase between incident beams can give rise to rich periodic patterns when overlapping more than three beams for surface plasmon holographic nanolithography.
