Treats every point in the starting field as a point source; the final field is the sum of contributions from all these sources. 2. Common Numerical Methods

Choosing a method depends on the required accuracy, the complexity of the geometry, and available computational power. Numerical Simulation of Optical Wave Propagatio...

Decomposes an initial optical field into plane waves, propagates each separately by applying a complex phase shift, and recombines them using an inverse Fourier transform . Treats every point in the starting field as
