Abstract

A new formulation of the classical scalar beam-propagation method is derived by use of the fractional order Fourier transform. The method relies on the fundamental fact that the coherence is transformed by a linear filter univocally connected to the filter acting on the electric field; building on this result, we solve exactly the problem of the passage of such fields through arbitrary lossless optical system characterized by their ABCD matrices.
