Improvements have been made to the traditional filters of industrial microwave ovens by means of new internal geometries. They are also significantly smaller than regular microwave ovens. According to Francisco Javier Clemente, their main advantages are their size, energy efficiency and the addition of cold compartments where foods are not heated.
The thesis involves three patents exploited by two companies. The one corresponding to the microwave oven is available worldwide and exploited by the companies Shieltronics and Halm HBVA. The other two are used by a Spanish firm, RBT Sistemas de Nueva Automatización. These two patents should lead to a reduction of microwave emissions by all kinds of materials as a result of the change in the geometry of the filters.
The research project has also been dealt with in six articles published by international magazines and presented at thirteen international conferences.
