Abstract

PURPOSE:To reduce the electrode index, to eliminate the affect of electrodes and to improve the performance, by constituting the correcting electrodes so that the plane waves incident to the side lobe are outputted as plane waves again and they can be passed under the metallic film of the equal amount.
