Abstract :
The behavior of Berenger perfectly matched layer (PML) for absorbing nonTEM (TE & TM) waves in rectangular waveguide is analyzed in this paper. The attenuation constant and the phase constant of TE & TM waves in rectangular waveguide filling with Berenger PML are given. It is shown that Berenger PML can be used in finite-difference time-domain (FDTD) simulation of rectangular waveguide operating at or near cutoff frequencies, due to the very small phase constant at these frequencies. A numerical example is given to show this.
