- Not exactly, to pick nits. First the wavelength of your usual
- 2.45 GHz microwave is about 12 cm. Second, the process is dielectric
- heating which acts on a bunch of biological materials including water
- and can be understood classically as the action of an electromagnetic
- field on a polarizable medium.
