✦ Synopsis

In this paper, the design of a dielectric multilayer around a dielectric sample in order to avoid the appearance of undesired reflections and achieve higher matching-efficiency values within multimode microwave-heating ovens is presented. The permittivity and geometric values for the sample surrounding layers are optimized by means of genetic algorithms (GAs) in order to maximize the system matching. Several dielectric-mould configurations are studied and the results show that the use of dielectric layers surrounding the product substantially improves the load matching.
