## xwp_petsc : X-ray wave propagation in PETSc

Code for evaluation of wave propagation (fourier and real space approaches) using PETSc. Works for 1D and 2D for free space and matter.

#### Currently implemented  :

- Full Array Fresnel Multislice : Iterate between slice projections diffraction and free space propagation

- Finite Difference method : Solve the Helmholtz PDE using TS integrator
