This work presents an alternative method for curing cork stoppers based on microwave radiation, which is energetically more efficient, where it is possible to accelerate the reaction rate and therefore reduce the cure time comparatively with conventional curing methods. The microwave energy is directly introduced in the volume of the dielectric material and as a consequence, the quality of the process is highly dependent on the uniformity of the electromagnetic field distribution along the material. That is, the non-uniformity of the heating is a potential problem with serious consequences. To understand this phenomenon, a perceptive of how electromagnetic field propagates and interacts with the material is essential. For this purpose, we simulated the heating microwave process using COMSOL Multiphysics®.
