INFORMATION PROPERTIES OF A ZONE PLATE

I. V. Minin, O. V. Minin

Abstract:
The paper reports a study of the information properties of a zone lens antenna. The focusing properties for a substantially off-axis point source are investigated. The number of image elements in a plane frame and on the best focusing surface are determined and the profile of this surface is evaluated. Estimates are given for the operating range and Q-factor of a zone plate.
