Abstract
A finite-difference time domain scheme for the analysis of H-plane waveguide discontinuities is described. The two-dimensional treatment of this kind of discontinuities and the use of a non-monochromatic excitation allow us to develop an efficient algorithm with a low demand of computer resources. The method is tested by comparing the numerical results for a right corner bend and a T-junction, the choice of the absorbing boundary conditions is discussed for each case.Keywords
