In this paper, we will discuss an advanced application of metasurfaces, the generation, enhancement, and control of nonlinear signal via nonlinear metasurfaces. We will introduce the computational methods for nanophotonic metasurfaces, focusing in particular on the approaches for the simulation of nonlinear processes.
