Abstract :
In this paper, the body-of-revolution finite-difference time-domain (BOR-FDTD) method is used to study the performance of a Fresnel zone plate in a focusing system. Results from a comparison of a zone plate with a doubly-hyperbolic lens will be presented to illustrate the benefits and limitations of the zone plate.
