Design of a microwave applicator for sterilization using multiobjective optimization and phase control scheme

In this paper, we present a multiobjective evolutionary approach to design a microwave heating applicator. The goal for the device is to heat the maximum amount of water spending minimum energy. A set of optimal solutions is obtained, the Pareto front. A decision-making strategy was applied for selecting the point that corresponds to the most efficient device. The efficiency is improved by using a phase control scheme to obtain constructive interference inside the load.
