Design of an automatic impedance matching system for industrial continuous microwave ovens. Part II: experimental results

The algorithm proposed in part I (see ibid., p.791-5) was carried out in an experimental test. This test is elaborated in order to make a fine tuning of the algorithm parameters and analyze the results. An artificial load was used, composed of a matched load with a mismatched device. The mismatch was obtained by varying the length of four screws positioned in a rectangular waveguide.
