The internet doesn't help.

Wtf is that?

It feels plasticky and hard. But I don't think it's happy to see me since it's broken in half and I probably did it when cleaning it.

If you help me figure out what it is, I will clean my microweave in return.

Edit: It's a Mica cover. TIL.

Mica cover does not stop radiation whatsoever. It stops boiling grease from your overheated sausage from drizzling onto the electronics.

It's still a bad idea to use a microwave without a mica cover, it's gonna stink with burning grease after a few uses.

Most microwaves do not have waveguide nowadays, the magnetron sits right behind the mica cover.
