Abstract (en)
The invention provides for a method for heating materials being capable of absorbing high-frequency electromagnetic radiation, in particular microwaves, by means of irradiating said materials with high-frequency electromagnetic radiation. In order to achieve an essentially consistent heating of the material and, in particular, to avoid hot spots in the material, the high frequency electromagnetic radiation is coupled into said material at a plurality of radiation areas by means of a plurality of incoupling means, the centres of said radiation areas being spaced apart from each other. The temperature of the material is measured in each of said plurality of radiation areas, and the radiation dose of said plurality of incoupling means is controlled, dependent on the respective temperature, in such a way that a substantially uniform temperature of the material is obtained in all of said plurality of radiation areas. The method is particularly useful for curing or crosslinking polymers or resins. Moreover, a device for carrying out such method is proposed.
