A new analysis of electromagnetic-field propagation is presented whereby the field-propagating step operators are derived from a direct method for solving Maxwell’s equations. This approach permits the accurate propagation of full-vectorial fields because it does not need approximations accompanied by a second-order derivative with respect to the propagating direction.
