PML boundary condition does not show TM modes

Hi there,

I am trying to simulate a waveguide structure, when I used metal boundary conditions I have both TE and TM modes. But when I switched to PML there is no TM mode. I used a different n (instead of use max index) but did not see any TM modes. What possibly could be the reasons for this?


Thanks
