Sample Movement Optimisation for Uniform Heating in Microwave Heating Ovens

A technique for improving the uniformity of heating patterns of dielectric samples in a multimode cavity is presented based on a strategic movement of the sample inside the microwave applicator. Different optimisation algorithms are compared to determine the best microwave irradiation period for eac...

Sumario:A technique for improving the uniformity of heating patterns of dielectric samples in a multimode cavity is presented based on a strategic movement of the sample inside the microwave applicator. Different optimisation algorithms are compared to determine the best microwave irradiation period for each sample position. A new optimisation procedure that minimizes electric field variance is also presented and assessed.
