Not really an answer, but here's some context...
In 1952, a paper called Tubes for dielectric heating at 915 megacycles said this, "Dielectric heating can be much faster at microwave frequencies. Because leakage radiation is large enough to interfere with communications, heating is best done at assigned frequencies. The bands at 915 and 2,450 megacycles are most useful."

- abainbridge 5y agoAh, OK, 1947. "The plan which is, recommended by the United States provides for certain discrete frequencies, with appropriate guard bands, for those industrial scientific and medical devices which cannot be shielded effectively. This assures a minimum disruption of vital communication services. The allocation of frequencies for this purpose is justified because of the tremendous investments in equipment and the public demand for the various services performed, together with the harmful interference to radio communications which would result if such devices were scattered indiscriminately throughout the spectrum. The frequencies proposed are: 13660 kHz 27320 kHz 40980 kHz 2450 MHz" http://handle.itu.int/11.1004/020.1000/4.62.51.en.108 http://handle.itu.int/11.1004/020.1000/4.62.51.en.108, page 628.
