Webb4 apr. 2024 · However, conventional OAM identification approaches are often complicated and costly. In this letter, a convenient method based on diffraction neural network (DNN) is presented for OAM states detection in the sub-terahertz (sub-THz) regime. The optimal phase distribution of the lens for OAM state detection is obtained from DNN training.
