A rigorous and simple method for analyzing a rectangular-groove guide using a Fourier-transform technique, which takes the field singularities at the edge of the guide into consideration, is presented. The convergence of the solutions is very fast and the accuracy improves significantly. It is shown that a mode-propagation constant with five-figure accuracy is obtained by solving a 7 × 7 matrix equation.
