【 摘 要 】

We present an extension of the discrete sources method for solving the time-harmonic Maxwell equations accounting for the non-local effect. The developed numerical scheme coupling the non-local hydrodynamic Drude model and the generalized non-local optical response model is described in detail. Numerical results computed for a single nonspherical particle and a linear dimer are presented. Our results demonstrate that the discrete sources method can be efficiently used to model the non-local effect in a wide range of 3D scattering problems. (c) 2019 Elsevier Inc. All rights reserved.
