Hi,
I am working on a rectangular structure, where I've created a PML boundary condition on all the four sides of the rectangle by creating a layer on its all sides. Also, inside it I've created a square and done a mapping inside it. For the entire geometry, I've chosen air as the material. I've created an inside port, from which I've given TE wave excitation. After simulating, I could find that reflection from the mapped square domain. How to avoid reflection in this case?
