Efficient absorbing boundary condition for UWB simulation in frequency dependent ADI-FDTD

UWB simulations require a very efficient ABC which can cope with evanescent waves. CFS-PML is the most complete ABC and can accommodate the high bandwidth of UWB and the evanescent waves coming from a lossy media. Although a CFS-PML formulation has been presented for FDTD and ADI-FDTD, no formulation exists for ADI-FDTD with Debye media. This paper proposed such formulation of CFS-PML to accommodate Debye media in the ADI-FDTD scheme. Further research is currently undergone to assess this ABC and results will be shown at the symposium
