Is it possible?
DC sputtering for the win. Magnetron sputtering [see Youtube for home made examples] does not use a microwave tube, it uses a special cathode with a magnet behind it to spiral the electrons causing more energetic impacts to the source target. Same spiral physics effect as in a microwave magnetron, just used differently. I guess spiral sputtering just didn't sound cool. Works gangbusters.
It's a misnomer. RF is not used.. Both Microwave driven MOCVD [What Kecked describes] and sputtering are slow and can result in a toxic mess at the hobby level.
There are people who do induction heating with susceptor materials to heat metals and ceramics for hobby processes in home microwaves. Basically RF induction heating. it's mostly a gimmick and great way to have a kitchen fire. I've tried it, a proper furnace wins every time.
Because of Amazon, high temerature furnaces and furnace materials are now cheaper then ever.

HMMMM, ask spyropyro about magnetrons
