Propagation characteristics of TE modes in non-uniform circular cylindrical waveguides for Gyro-TWT applications

This paper discusses the propagation characteristics of TE modes in non-uniform circular cylindrical waveguides for Gyro-TWT applications. The theory developed in this paper applies more particularly to tapered sections of waveguide having a gradually changing taper angle to connect waveguides of different cross-sectional dimensions for the preferential transmission of a particular mode. The operating mode is carefully selected with due consideration of design constraints/goals. The TE
₀₁
mode is selected as an operating mode for the present study. Coupled ordinary differential equations have been derived for the waveguide which are then solved numerically to determine the electromagnetic field configuration inside the waveguide.
