Abstract

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