Inverse Design of Nanoparticulate Materials
Advanced Materials, EarlyView.Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes
Advanced Optical Materials, EarlyView.We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

A comparison of FDTD-PML with TDIE
IEEE Transactions on Antennas and Propagation, 2002 Presented in this paper, is a comparison of two popular numerical techniques, viz. the finite-difference time-domain method and the time domain integral equation method, for electromagnetic-scattering problems. The comparison is made via standard canonical shapes, a cube, and a sphere, to address the factors affecting accuracy, efficiency, and the ...

Quantifying numerical dispersion in non-orthogonal FDTD meshes [PDF]
, 2002 Numerical electromagnetic models such as FDTD are widely used for the design and analysis of structures, including antennas. Numerical dispersion is one of the main sources of error that degrade the accuracy of the results-for each structure of interest,

Advanced Optical Materials, EarlyView.Here we use a template‐assisted self‐assembly approach of metal colloids onto metal films to produce hybrid plasmonic metasurfaces that integrate nanoparticle‐on‐mirror cavities with periodic metal colloid arrays. The resulting coupling between gap plasmons and grating‐coupled surface plasmon polaritons enables programmable hybrid modes with tailored ...

FDTD modelling of reverberation chamber
Electronics Letters, 2005 The finite-difference time-domain (FDTD) method is applied to the simulation of a reverberation chamber. The real losses of the reverberation chamber are taken into account in a post-treatment process. The predicted results are compared with measured data and good agreement is reported.

Model of light bullet propagation in LiF crystal
Компьютерная оптикаA numerical model is developed for simulation of the propagation of a light bullet in LiF crystal and the formation of a colored track. The model reproduces the previously observed longitudinal oscillations in the concentration of color centers in the ...
