While skimming through Dielectric heating, I read that they use microwaves to charge the plates. How do they do that?

Hello Abdel, Perhaps Any reference would be good, so that many users could try to answer. :-) – Waffle's Crazy Peanut Oct 21 '12 at 8:15

Absolutely. This is how a microwave ovens work (at least when you put metal in them). Microwave ovens emit electromagnetic radiation in the microwave region (roughly $2.4 \, \mathrm{GHz}$) Metal plates in a microwave oven act as antennas and the electromagnetic radiation induces a huge electric current.

If you are looking for specific details on how current is induced, any antenna theory will help. If you're interested in the power transfer, check out wireless power.
