The microwave oven principle is quite simple, each microwave oven a magnetron, which generates alternating power field, The water molecule, or any polar molecule within the food will vibrate with the power filed and generate heat. so all polar molecules, not only water, but also amino acids, lipids and proteins - will vibrate and are forced to align themselves with the rapidly changing alternating electrical field.
The vibrating frequency is the microwave frequency, typically about 2.4 billion times per second, which your cell phone or your home wifi also works around this frequency range.
The phenomenon of microwave heating caused by microwaves was discovered in 1946, and the first microwave oven was built in the 1950s by the Raytheon copmany.
