Abstract :
The finite difference time domain (FD-TD) method is applied to model discontinuities in square coaxial waveguide, particularly a T-junction in square coaxial cable is studied. The separation of the computation domain in a total field region and a reflected field region, and the use of a synthetic excitation constituted of a great number of monochromatic waves allow us to develop an efficient algorithm. Numerical results are given for the scattering parameters of a T-junction in the band 1-6 GHz
