Background. At the end of the last century, it became necessary to solve the problem of excitation of unsteady fields in closed and open electrodynamic structures. In the 1980s, the Department of Theoretical Radiophysics proposed an alternative to the Fourier method, the mode basis method for closed hollow resonators. In this paper, we consider an electrodynamic problem on the excitation of an unsteady field in an open cylindrical waveguide. At the very beginning, the original system of Maxwell'
