Efficient Electromagnetic Simulation of Shielding Mechanisms in Microwave Ovens
The door to a microwave oven forms part of the heating cavity, allowing access to the oven interior. The seal around the door is never perfect, so electromagnetic fields will leak out of the oven, potentially interfering with other electrical equipment or exceeding SAR safety limits for power levels in human operators. Oven designs have to meet legal requirements for the amount of power which can leak beyond a certain distance from the oven (due to human exposure concerns), and also have to meet electromagnetic compatibility (EMC) requirements. This article discusses how electromagnetic simulation can be used to design effective shielding mechanisms in order to adhere to these standards.
