Artificial subwavelength structures called metamaterials (MM) are one of the most promising approaches in modern photonics for full control of light with respect to its polarization and spectral properties. By using MM made of complex shaped 3D elements almost arbitrary optical functionalities can be integrated into thin films. However, as the fabrication of 3D MM is usually difficult, complexity of the optical response might be achieved instead by choosing 2D metasurfaces (MS) and stacking them. In this contribution, we propose a method for efficiently treating and optimizing stacked complex homogeneous MS to create integrated, highly functional optical devices. A theoretical framework for fast numerical calculation is given by means of a modified scattering matrix formalism providing full information about phase, amplitude and polarization of the desired reflected and transmitted fields. As we will show with some examples this will pave the way towards simpler structures and easier fabrication, while maintaining and even increasing the range of accessible optical functionalities. A preprint of the paper is available at http://arxiv.org/abs/1511.09239.
