Finite element analysis of the cutoff characteristics of dielectric-loaded inverted trapezoid ridge waveguides
In order to find a dielectric-loaded inverted trapezoid ridge waveguide with the optimum cutoff characteristics
a dielectric-loaded inverted trapezoid symmetrical dual-ridge waveguide is presented.Its cutoff characteristics in the TE mode
i.e.the cutoff wavelength of the main module and single-mode bandwidth
are calculated with the help of MATLAB by using the finite element method.The dominant mode field pattern is drawn
the relationship between the cutoff characteristics and the relative dielectric constant analyzed and the relationship curve plotted.These results provide certain theoretical basis and the reference data for the design and engineering applications of dielectric-loaded waveguides.
