Hi everyone,
I have a problem with PML for circular waveguide in HFSS.
For testing PML, i just created an empty waveguide and excited it with waveport. At the other end of waveguide, i tried to end it with perfect matched layer.
What I ought to see whenever I plot the magnitude of S11 is a constant graph with only "0" value. Because there must be no reflection at the end of the waveguide and all fields are to be absorbed. But I obtain very different values rather than 0. What can I do to absorb fields properly.
I attached my design file. I thank you in advance.
