Well dont know If you are serious but I just googled it and the only way you should use metal in a microwave, is by using a flat piece under your pizza for example.
It helps to make it somewhat crunchy. Or you can actually protect parts which you dont want to get overheated. Quite useful tips actually.
And yes the metal reflects the waves.
Here:
"Microwaves work thanks to magnetrons. This technology, originally designed for military radar systems, generates very short, high frequency radio waves from standard AC current—usually around 2.5 gigahertz. That frequency is just right for being absorbed by water, fat, and sugar molecules within organic matter. This extra energy causes them to vibrate at very high speeds, which in turn generates waste heat that actually cooks the food."
Since a radar can only track objects which reflect the waves its sending, it makes sense.
