Abstract :
Finite element method is introduced to analyze the transmission characteristics of depressed trapezoidal-ridge waveguide in this paper, solves the cutoff wavelength of the dominant mode, bandwidth and field patterns of the typical model size, discussions the influence of the trapezoidal-ridge size on the transmission characteristics. Some numerical results and figures are presented.
