| Abstract: | In the study,the variable regularity of cutoff wavelength and bandwidth of the dominant mode are obtained when the position,width and height of the ridge are changed by applying the finite-difference time-domain(FDTD) method to the analysis of the transfer characteristics of single-ridge waveguide with the ridge on the short side.The data can be used as a reference for their engineering application.Compared with conventional single-ridge waveguide,it shrinks in cutoff wavelength and singe-mode bandwidth. |
