Simulating Diffraction on a Series of Amplitude-Phase Masks for Experiments at the Novosibirsk Free Electron Laser

详细

The problem of calculating the electromagnetic field of directional radiation passing through a system of amplitude-phase masks arises in many studies. This work describes the WaveThruMasks software package written for planning and analyzing experiments on the terahertz radiation of the Novosibirsk free electron laser. An example is given of using the package to analyze the results from experimental studies of the diffraction of Bessel beams with orbital momentum on two-dimensional gratings.
