Abstract
This paper discusses a discrete form of wave equation applied to nonorthogonal and irregular grids. Modifications to the standard finite difference algorithm are introduced, preventing substantial loss of accuracy when the grid is deformed. The algorithm is used to find cutoff frequencies of rectangular waveguides rotated with respect to the mesh.
