This research proposes an optimization framework that integrates the FDTD method and Genetic Algorithm,aiming to enhance the reflective performance of optical thin films.It selects a three-layer thin film structure as the research object,employs the FDTD method to calculate the reflectivity of the thin film structure and uses it as the fitness function in the Genetic Algorithm.By combining these two methods,we effectively search for optimized parameters within a multi-dimensional design space,significantly reducing the reflectivity of the thin film.This method not only reduces computational co...
