A new approach, the multipole theory (MT) method based on the subregion solution, is presented for the computation of cutoff wavenumbers in waveguides with sharp metal edges. The eigenvalue equation related to the subregion solution is derived. The results of test calculations are listed for several waveguides whose cross sections contain one or more sharp metal edges. Excellent agreement with results obtained previously is demonstrated. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 101–105, 2001.
