Microwaves, being natural physical entities, were never "invented," rather, their presence was discovered. Microwaves are a small component of a very broad spectrum of electromagnetic fields which includes colors, UV, radio waves, and even "heat waves" (called infrared). To ask when microwaves were invented is like asking when the color blue was invented. The microwave oven was patented and produced in 1945 by Percy Spencer.
