WaveOpticsPropagation.jl

Propagate waves efficiently, optically, physically, differentiably with Julia Lang. Those functions are fast and memory efficient implemented and hence are suited to be used in inverse problems.

Installation

Officially registered, so install with:

julia> using Pkg; Pkg.add("WaveOpticsPropagation")

Features

Implemented

Propagate (electrical) fields based on wave propagation
Propagations
- [x] Angular Spectrum Method of Plane Waves (AS)
- [x] Fraunhofer Diffraction
- [x] Scalable Angular Spectrum propagation
- [x] Shifted Angular Spectrum propagation
- [ ] Fresnel Propagation with Scaling Behaviour (no priority yet, PR are welcome for that. In principle very similar to the other methods.)
[x] CUDA support
[x] Differentiable (mainly based on Zygote.jl and ChainRulesCore.jl)

Vectorial propagation in free space is just a propagation of each of the components. Right now, this is not a priority and is not implemented yet. But of course, each vectorial component can be propagated separately.

Development

Contributions are very welcome! File an issue on GitHub if you encounter any problems. Also file an issue if you want to discuss or propose features.

There is the outdated PhysicalOptics.jl which provided similar methods. For geometrical ray tracing use OpticSim.jl.
