In this paper, we propose a new quantitative method for determining the statenumber l of the beam carry Orbital Angular Momentum (OAM), both individuallyand in a sum in a combination of l= -3, -2, -1, 0, 1, 2, 3 based on analysis ofthe S21 system parameters. This allows the receiving device to be tuned toreceive beams with a specific OAM state. Radio waves carry OAM have a frequencyof 80 GHz. The work is an experiment on a computer model. Simulation of beamswith different states l, as well as determination of S system parameters, iscarried out using the software product SCT Studio, and addition orsuperposition of S parameters of beams with different states l was produced bymeans of the software product Matlab.
