Study of an optical nanolens with the parallel finite difference time domain technique

Authors


Abstract

[1] In this paper a three-dimensional dispersive finite difference time domain based on the message passing interface architecture is applied for the full wave modeling of a metallic nanolens operating at optical frequencies. The subwavelength imaging potential of the nanodevice is thoroughly studied. The issue of symmetry in the nanolens is exploited, which is shown to have a direct result at the dynamic behavior of the nanolens.
