In order to realize the modeling and numerical simulation of the electromagnetic field distribution and wave propagation in interconnects of interposers for three-dimensional integration, the Finite Difference Time Domain(FDTD) method is used in this paper to reveal the propagation of two-dimensional TE(Transverse Electric) wave. Variations of the magnetic field at the boundary are compared when adding Mur and PML(Perfectly Matched Layer) absorbing boundary conditions respectively. The error curves and isophasal lines are plotted to validate the absorbing performance of these two boundary conditions. The results show that PML can be used as the absorbing boundary of a two-dimensional TE wave to ensure a more appropriate absorbing effect in engineering simulation.
