SDOSS is a MATLAB code package to implement the Rayleigh-Sommerfeld diffraction formula. SDOSS implements two types of method:

• Direct integration [1].
• Angular spectrum [2, 3].

In our paper, we used the angular spectrum method to produce most of the simulations.

Demos are:

• demo_sdoss.m demonstrates the basic usage of the package.
• demo_theory_test.m reproduces Figure 4 in paper [1].
