Efficient Electromagnetic Simu- lation of Shielding Mechanisms in Microwave Ovens

چکیده
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 fi elds will leak out of the oven, potentially interfering with other electrical equipment or exceeding 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.

متن کاملElectromagnetic radiation from microwave ovens.
Electromagnetic radiation from microwave ovens in Saudi Arabia was investigated by means of a field measurement survey. The survey was carried out for 106 ovens used in households and restaurants in Riyadh city. Ovens were between 1 month and 14 years old with operating power ranging from 0.5 to 4.4 kW. One oven was found to leak more than the 5 mW cm(-2) limit specified in the standard. Fiftee...
متن کاملModeling of Susceptor Assisted Microwave Heating in Domestic Ovens
Susceptors are used in microwavable food packages to facilitate preferential heating. Modeling of susceptor assisted microwave heating in domestic ovens was performed using radio frequency and heat transfer modules of COMSOL Multiphysics 4.2. Two different approaches (domain discretization and transient boundary condition) were studied for taking into the account of discretizing thin susceptor ...
