What are the components of a microwave oven?

• High voltage power source, commonly a simple transformer or an electronic power converter, which passes energy to the magnetron
• Stirrer, which converts high-voltage electric energy to microwave radiation
• Magnetron control circuit (usually with a microcontroller)
• Waveguide (to control the direction of the microwaves)
• Turntable
• Cooking cavity
