Abstract
Split-step propagation algorithms are widely used to model the propagation of fields in complex environments. Typically one of the slowest steps in such an algorithm is the computation of the forward and inverse transforms. Chirp versions of the sine and cosine transforms were derived, to allow modification of the number of points used in the transforms according to the detail needed in a particular region.
