The diagrams I’ve seen show the wave stirrer on the roof. The microwaves I’ve seen have the ceramic plate on the side where the magnetron is so there’s no space for a stirrer.
if the diagram’s any good, it should show the wave stirrer in the roof rather than on the ceiling of the food chamber. There’s typically a waveguide to take the microwaves from the magnetron to the top of the chamber, then the wave stirrer is at the end of the waveguide to vary the angle that microwaves enter the chamber at. There’s usually something to stop food splashing/spraying into that section, though, e.g. an extra few centimetres of waveguide afterwards with a bend in it.
I understand what you’re saying, I’ve just not seen one with any indication of a wave stirrer. They all just shoot the beams from the magnetron through a ceramic plate on the side if the microwave. The top interior of the microwaves I’ve used (even one ones from Samsung and LG) had no holes or vents. Maybe it’s just an American thing?
I’ve never used or dissassembled an American microwave, so wouldn’t know about anything American-specific.
Having a ceramic plate at the end of the wave guide isn’t evidence that there’s not a wave stirrer on the other side of the plate or part way along the wave guide. As far as the microwaves are concerned, the ceramic plate is a hole, though, because (unless the manufacturer selected a stupid material), it should be about as transparent to microwaves as the air is.
