Theoretically and Ezperimentally Investigation of Sparking of Metal Objects inside a Microwave Oven
Over the past years, some microwave oven experiments have been done by placing non-food objects such as metal objects, CDs, lightbulbs and etc. in the microwave oven cavity 1-4. It is well understood, when a metal object is placed inside the oven cavity, sparking will result. Here, we have theoretically investigated the sparking of metal objects within the microwave oven, based on the electrostatic and alternating field. The resonant modes characteristics of both TE and TM electromagnetic fields in the oven cavity are determined. An approximate analysis for electric fields around the metal disks and sharp edges is carried out by solving Laplace equation in polar and elliptical coordinates. Some experiments are done for CD-ROMs and several types of metallic rings and wires. They have shown a good agreement with the theoretical predictions.
