ABSTRACT
The paper presents results of investigation of some features the specifics of the electron flow interaction with the travelling electromagnetic wave on a basis of nonlinear theory of authophase travelling wave tube with azimuthally asymmetric wave and focusing field in azimuthally asymmetric authophase travelling wave tube mode, when the cyclotron frequency is higher than doubled signal circular frequency. The software for determination of basic characteristics of the TWT has been created. The electronic efficiency of 95,6% with 40 dB gain in one-stage design was reached.
