Study on the Transmission of Multi-Ridge Waveguides based on Finite Element Method

Finite element method is introduced to analyze the transmission of multi-ridge waveguide, solves the cutoff wavelength of the dominant mode and field pattern of the typical model size in double ridge waveguides, triple ridge waveguides and quintupling ridge waveguides, analyzes the changes of the transmission by changed the multiple of ridges, the ridge width, the ridge height and the distance between ridges. Some computational data and figures are presented.
