Using finite-difference method for the Helmholtz equation
this paper investigates the influence of the ridge in a novel single-ridge rectangular waveguide on the transmission characteristics of the waveguide when the ridge is in the central part and its dimensions vary.It calculates the cutoff wavelength λc and single-mode bandwidth B(λc /λc1) when the ridge dimensions vary and gives the field patterns of TE10 mode and TE11 mode and the curve corresponding to the relevant effects of the transfiguration.By comparing with the conventional waveguide
it points out the advantages and disadvantages of the new single-ridge rectangular waveguide.
