ASPECTS REGARDING THE PROCESSING OF DIELECTRIC MATERIALS IN A MICROWAVE FIELD

Abstract

The paper includes the main results obtained in the domain of the processing of dielectric materials in a microwave field. It has the character of an applicative research, the obtained results being of practical use, with the main purpose of optimizing the functioning of some heating devices in a microwave field. This analysis is efficient but it implies the exact knowledge of the dielectric and thermal properties of the material that is to be processed, and also the dependence of these properties on the temperature. The main problem we follow is represented by the homogeneity of the field and, consequently, of the temperature in the material.
