By using a rigorous numerical technique that is applicable to calculations of modes in waveguides for the TM case, the effects of the periodic rectangular, triangular, sinusoidal, and Gaussian random rough surface on the rectangular waveguide are discussed. The effects of the parameters of the roughness on the mode cutoff frequencies and field distribution are considered, including the height, width, and period of the grooves, the standard deviation of height and correlation length of the Gaussian roughness.
