Jc. Olivier et Da. Mcnamara, ANALYSIS OF MULTIPORT DISCONTINUITIES IN WAVE-GUIDE USING A PULSED FDTD APPROACH, IEEE transactions on microwave theory and techniques, 42(12), 1994, pp. 2229-2238
A pulsed finite-difference time domain (FDTD) approach for computing t
he scattering parameters of multiport waveguide discontinuities and ju
nctions is presented. Wideband absorbing boundary conditions (ABC's) n
ecessary for implementation of the technique are derived, Applications
of the technique are presented, and computed results are compared to
measurements for several examples.
