Reconfigurable intelligent surfaces (RISs) have recently received significant interest as a solution to enable a programmable wireless signal propagation environment. They can also be mounted on non-flat sur- faces. An open question in this topic is the phase optimization of RIS when it is imple- mented on a non-plane surface based on a set of experiment data.

In this research, we are interested in approximating the non-plane surface and then designing a codebook tailored for our approximation. To do this, we first train a neural network to estimate the unknown parameters of the approximated function by collecting received power in each grid after applying a codebook specific for the plane RIS. More specifically, we aim to exploit deep learning to map the distortion in the plane surface to the known different groups of non-plane RIS with a quadratic distortion.
