Abstract :
The perfectly matched layer (PML) boundary condition is employed in conjunction with the 3D finite-difference frequency-domain method (FDFD) for S parameter calculation of microwave devices. We find a residual reflection error, which is related only to discretization at the PML interface. The paper presents a systematic investigation of this parasitic effect and its origin.
