Prerelease. First stable release planned for April . Until then, accuracy not validated. Report bugs on Github - we usually respond within a day

Overview

Generative design meets Maxwell's Equations. GPU and automatic differentiation (AD) compatible FDTD package in Julia for inverse design & topology optimization in semiconductor photonics, acoustics and RF. Uses AD by Zygote.jl for adjoint optimization. Integrates with Jello.jl to generate length scale controlled paramaterized geometry . Staggered Yee grid update with fully featured boundary conditions & sources in 1d/2d/3d. Customizable physics to potentially incorporate dynamics like heat transfer, charge transport.

Installation

Install Julia preferably with VSCODE. Then add our package via

using Pkg
Pkg.add(url="https://github.com/paulxshen/Luminescent.jl")
Pkg.add(url="https://github.com/paulxshen/LuminescentVisualization.jl")

LuminescentVisualization.jl contains visualization utilities. If you're running tutorials also add

]add UnPack, BSON,DataStructures, StatsBase, Zygote, Jello, GLMakie, CoordinateTransformations,AbbreviatedStackTraces,CUDA,Flux

Omit CUDA if you don't have NVidia GPU

Quickstart

Please refer to the first tutorial
