Abstract
The present contribution is concern with an exact frame based expansion of planar initial time-harmonic electromagnetic fields. The propagating field is described as a discrete superposition of tilted and shifted electromagnetic beam wave objects over the frame spatial-spectral lattice. Explicit asymptotic expressions for the electromagnetic Gaussian beam propagators are obtained for the commonly used Gaussian windows.
