A direct finite-difference time-domain (FD-TD) method is applied to the analysis of waveguide discontinuities. Both the validity and efficiency of the method ate demonstrated in the case of an H-plane right-angle corner bend with and without dielectric loading. Comparisons of the present results with those obtained using the spectral-domain methods are made and they are shown to be in good agreement.
