Hello, I encountered such a problem: TM01 mode was excited to two circular waveguides. One has a full circular discontinuity and the other has a partial circular discontinuity shown in the figure 1. Results are shown in figure 2. The peak value correspond to the reflection from the discontinuity but I am confused about the reflection component behind the peak when using a waveguide with partial circular waveguide. It is just like there is a source continuously generating the reflection signal. I observed this in both simulations and experiments. I will appreciate your comments.
