A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating .
Percy Spencer, an engineer working for American defense contractor Raytheon, accidently discovered a new use for radar technology in the mid-1940s. While standing near an active magnetron, which ...
The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...

Yes, the microwave oven was invented accidentally, when a test for a magnetron melted an engineer’s snack in 1946.. Raytheon engineer Perry Spencer “knack for finding simple solutions to ...
Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed.
GE Appliances has a long history of cooking innovation and is responsible for creating the first self-cleaning oven as well as the first over-the-range microwave. [7] GE Appliances was also the first manufacturer to launch a suite of WiFi-connected appliances as well as the first suite of appliances that work with IFTTT. [8]
The history of metamaterials begins with artificial dielectrics in microwave engineering as it developed just after World War II. Yet, there are seminal explorations of artificial materials for manipulating electromagnetic waves at the end of the 19th century. [ 1 ]
