Abstract A finite-difference frequency-domain(FD-FD) method in non-orthogonal coordinate is presented for the eigenvalue problems of waveguide. The numerical discrete mesh of the algorithm can fit the arbitrary boundary well. In this paper the cut-off frequencies of modes of waveguides are calculated via given eigenvalue equation. The results show good agreement with those from other sources.
