Özet

We present computationally intensive electromagnetic analysis of metamaterials involving deformed nanowires. Random deformations are introduced to modify perfect nanowires in order to investigate the effect of geometric deviations on scattering properties of optical metamaterials. Numerical simulations of realistic structures of finite extent are performed accurately and efficiently using a rigorous simulation environment based on surface formulations and the multilevel fast multipole algorithm (MLFMA). Statistically common results of deformations, such as forward-scattering enhancements, are demonstrated on realistic metamaterial models.
