Analysis of the effectiveness of power equations in the description of electron-wave processes in the amplifier model based on the smith-purcell effect
We present the comparative analysis of different approximations used to obtain the dispersion equations in the form of power polynomials, which allow to describe the electron-wave processes in the amplifier system an open waveguide with periodic structure and an electron beam. Shown, that the amplif...

| Summary: | We present the comparative analysis of different approximations used to obtain the dispersion equations in the form of power polynomials, which allow to describe the electron-wave processes in the amplifier system an open waveguide with periodic structure and an electron beam. Shown, that the amplifier model described by the analytical third- and seventh-order dispersion equations is the most evident one from the physical point of view. These equations allow to take into account the basic characteristics of electrodynamic system and electron beam, which interacts with a bulk wave of the investigated quasi-optical system. |
