This paper presents a microwave amplifier device using a traveling-wave tube as an example and depicts the general modeling methods for resonant slow-wave systems (a periodic waveguide with an electron beam). An algorithm for numerical simulation of impulse processes using the direct Euler method in such systems based on the equations of an equivalent electrical circuit is developed. Based on it, software that allows time-efficient method of the periodic waveguide modeling with various input parameters and outputting the signal parameters in an equivalent circuit in real time is built. The calculations showed good performance, consistency with the results of analytical calculations of the reviewed scientific papers and accuracy acceptable to the pre-simulation algorithm.
