Rigorous analysis of deformed nanowires using the multilevel fast multipole algorithm

We present accurate full-wave analysis of deformed nanowires using a rigorous simulation environment based on the multilevel fast multipole algorithm. Single nanowires as well as their arrays are deformed randomly in order to understand the effects of deformations to scattering characteristics of these structures. Results of hundreds of simulations are considered for statistically meaningful analysis of deformation effects. We show that deformations significantly enhance the forward-scattering abilities of single and arrays of nanowires, while the enhancement factor of an array depends on the number of elements.
