Abstract :
We propose the implementation of perfect matched layer (PML) boundary conditions for the 2-D envelope finite element (EVFE) technique. The performance of PML is tested for different excitation modes and number of layers. It shows an overall 50 dB absorption with a 16-layer absorber. Furthermore, we employ the EVFE technique with PML boundary condition to solve the scattering problem and the results agree well with the theoretical value.
