Abstract

The optimization of Fresnel zone plates using a genetic algorithm and a the body‐of‐revolution, finite‐difference time‐domain simulator is studied. This technique is applied to zone plates for use in a free‐space, focused‐beam system to measure the electrical properties of materials. The results are compared with a traditionally designed zone plate and a doubly hyperbolic lens. © 2009 Wiley Periodicals, Inc.
