%X In most of microwave heating applications obtaining uniform heating patterns
in certain regions of the applicator is a key issue. In this paper, the proposed solution for
achieving electric field uniformity consists of designing the configuration of the feeding
system in a multimode cavity by means of Genetic Algorithms. The feeding system is
constituted by waveguides or slots arrays. The electric field pattern inside the cavity
depends on the location of these sources and an improvement in the electric field
uniformity on the product can be obtained by means of a proper design of this feeding
system. Results for the curing of epoxy resin over a marble slab are presented and they
show a significant improvement in the electric field uniformity over the epoxy resin.
