Abstract :
An explicit vectorial beam propagation method, based on the iterated Crank-Nicolson scheme is developed and utilized to solve electromagnetic wave propagation problems in large-scale structures. A full wide-angle extension is studied, based on a direct calculation of the one-way differential operator only in the first propagation step, together with a fast modification along the propagation axis, to account for material and structure variations.
