Abstract
We review the fast Fourier transform beam propagation method (FFT-BPM) that is commonly used to describe diffraction of electromagnetic wave s and introduce a time-domain version that takes into account arbitrar y longitudinal index profiles, as well as transverse effects. This met hod can describe all relevant aspects of paraxial propagation in linea r or nonlinear media. That is, the technique can handle transmission, diffraction, and, in particular, reflection of electromagnetic waves.
