Abstract
We use a 3-D parallel processing software based on the FDTD method to efficiently simulate the EM problem with an ill -conditioned computational domain. Advanced PML boundary condition allows us to use several cells of white space between the object and domain boundary and can generate the accurate results. A network card and a PEC sheet with a special slot are used to verified the proposed technique for the ECC (envelope Correlation Coefficient) and the transmitted power calculation. The simulation results match well with the other methods and measurement data.
