A modular implementation of dispersive materials for time-domain simulations with application to gold nanospheres at optical frequencies

Time domain simulation of dispersive materials from microwave to optical frequencies

“…The ADE approach is advantageous as compared to the RC approach because of its ability to handle nonlinear dispersive materials. In terms of accuracy, PLRC and ADE are comparable and are most commonly used approaches [5] [8]. In this paper, as an example we use only ADE approach.…”

“…After getting dispersive models in the form of equations (11), (12), (14), (16), (18) and (20), implementation of the ADI-FDTD method becomes simple and standard procedure [6] can be adopted. Above dispersive models can be applied to wide range of applications in the areas of RF/microwave, biomedical, metamaterials, photonics, and plasmonics [1] [8][9][10].…”

A 3D curvilinear discontinuous Galerkin time-domain solver for nanoscale light–matter interactions

“…We compare the results from DGTD simulations with the Mie solution of the problem. The latter is calculated with a Matlab script written by Dirk Baumann [28]. To conduct this study, we build three meshes M1, M2 and M3 with gmsh, for which the geometry of the sphere is meshed with an increasing precision (the mesh characteristics and a visual representation are respectively given in Table 3 and Fig.…”

Implementation of the FDTD Method Based on Lorentz-Drude Dispersive Model on Gpu for Plasmonics Applications

“…In order to model them accurately, different dispersive models have been incorporated into Maxwell equations [13,[16][17][18][19][20][21][22][23][24][25][26][27][28]. Most of the available dispersive models are in frequency domain, so as to make them consistent with time domain methods different approaches such as recursive convolution (RC), piecewise linear recursive convolution (PLRC), z-transform and auxiliary differential equation (ADE) [13,18,[24][25][26] are used. PLRC and ADE are most commonly used approaches due to their accuracy and efficiency.…”
