Abstract :
A finite-difference time domain scheme for the analysis of H -plane waveguide discontinuities is described. The two-dimensional treatment of discontinuities and the use of a nonmonochromatic excitation allow the authors 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
