Abstract 

The use of RF and microwave heating techniques implies to take into account the electromagnetic compatibility of the generators and the equipements for heating with the radio services already installed or in project, but also with all surrounding nearby electronic equipement.

In 1992, the world Administrative Radio Conference (WARC) allocated the 2.4835 - 2.500 Ghz band to Mobile Satellite Service (Space to earth) all over the world. But the 2.400 - 2.500 Ghz band is also allocated to ISM (Industrial, Scientific and Medical apparatus). This paper scans the leakage of an oven and suggests some technical improvement in order to reduce it.

Keywords : Electromagnetic Leakage; Microwave Ovens; Mobile Satellite Service; Transitory state.
