Abstract :
A H-T waveguide junction with an iris is simulated by use of FDTD method. For saving the memory and improving the efficiency, a modular approach and a PML exciting source are applied. From the result of electromagnetic fields, the scattering parameters of the junction are extracted by means of discrete Fourier transform, which have a good agreement with the results of planar circuit method.
