HFSS boundary: what if there no boundary?

Hi, all,
A dumb question: usually we need to specify a boundary condition for our model if HFSS. E.g. if we don't want any EM reflected back, we assign radiation or PML boundaries at the faces of an airbox. However, what if I do not assign any boundary conditions? That is to say, I only have an air box and don't assign it as any boundaries. How will the HFSS treat the material outside the air box which I haven't really specified. Will all of the EM be reflected back once it reaches the faces of the the air box? Thank you!

Correct, your airbox will be surrounded by a PEC, so you will have a resonator box inside the airbox volume.
