## Abstract The optimization of Fresnel zone plates using a genetic algorithm and a the bodyโofโrevolution, finiteโdifference timeโdomain simulator is studied. This technique is applied to zone plates for use in a freeโspace, focusedโbeam system to measure the electrical properties of materials. Th
