[0002] Microwave ovens are very common in modern life. Typically, a microwave oven uses a single magnetron to emit microwaves. When microwaves emitted by a single magnetron reach food, they heat the food from only one direction, easily leading to uneven heating. Furthermore, relying on a single microwave source for heating results in low heating efficiency.
