Description

technical field [0001] The invention belongs to the technical field of traveling wave tube simulation, in particular to an Euler method for simulating the linear injection wave interaction of a traveling wave tube. Background technique [0002] Traveling wave tube is one of the most widely used vacuum electronic devices, widely used in satellite communication, radar, electronic countermeasures and other fields. With the rapid development of my country's aerospace industry, there is a very urgent demand for the development and production of space traveling wave tube amplifiers. Among them, the linear theory of traveling wave tube can satisfy the simulation of the first 85% of the tube length of traveling wave tube, and it has the characteristics of fast calculation speed and small memory consumption. However, the traditional linear theory of TWT (such as Pierce small-signal theory) has low calculation accuracy in the linear region, which will directly affect the design of TW...
