Hello,
I simulate microstrip configurations, normally using metal boundary.
For open structures the boundary has to be sufficiently far from the strip.
This results in large calculation rooms, with many senseless mesh cells.
I think about it, if I can reduce the calc. room using the open boundary (perfectly matched layer PML).
My big metal box has, in some cases, only small waveguide ports (due to stabilty and higher order modes problems); so the incident wave can only leave the domain through this small ports. The rest of the wave will be reflected.
Using PML, every wave, which contacts the boundary will be absorbed (not reflected).
I already saw many antenna models using PML, but never a strip configuration.
Any ideas ?
Thanks
