Abstract :
A pulsed finite-difference time-domain (FDTD) approach for computing the scattering parameters of multiport waveguide discontinuities and junctions is presented. Wideband absorbing boundary conditions (ABC´s) necessary for implementation of the technique are derived. Applications of the technique are presented, and computed results are compared to measurements for several examples
