Envelope - Finite Element (EVFE) Technique in Electromagnetics with Perfectly Matched Layer (PML)

摘要

In this paper, the perfectly matched layer (PML) has been implemented into the Envelope Finite Element (EVFE) technique. The PML performance tests show that it can provide sufficient absorption of the incident waves both in 2D and 3D cases. The 3D guided wave structures are efficiently analyzed by the EVFE technique with the PML boundary condition. Furthermore, a new plane wave excitation scheme inside the PML boundary with EVFE technique is also presented here for the analysis of scattering problems, and the numerical examples validate the formulations.
