Computational Electromagnetic Analysis of Deformed Nanowires Using the Multilevel Fast Multipole Algorithm

We consider computational analysis of deformed nanowires and their arrays using a full-wave simulation environment based on integral-equation formulations and the multilevel fast multipole algorithm (MLFMA). Without requiring any periodicity assumptions, MLFMA allows for fast and accurate simulation...

description We consider computational analysis of deformed nanowires and their arrays using a full-wave simulation environment based on integral-equation formulations and the multilevel fast multipole algorithm (MLFMA). Without requiring any periodicity assumptions, MLFMA allows for fast and accurate simulations of complex nanowire structures with three-dimensional geometries and random deformations. We present the results of hundreds of simulations, where deformed nanowires are considered as isolated, as well as in array configurations, and their scattering characteristics are compared to those of non-deformed ones. Based on the simulation results, we rigorously investigate common effects of deformations on scattering properties of nanowires and identify strong field enhancements in forward-scattering directions.
