Double-sided split-step MM-wave Fresnel lenses: Design, fabrication and focal field measurements
Yurchenko, V.; Ciydem, M.; Gradziel, Marcin; Murphy, J.Anthony; Altintas, A.
Design, fabrication and focal field measurements of W-band Fresnel lenses to produce well-shaped Gaussian beams in the focal domain are presented. Two lenses, one of Teflon and another of Polyamide, have been compared in their performance with a double-sided Fresnel lens of different design, with full height of Fresnel steps. Experiments show that a good focusing ability of all the lenses is achieved. They produce the target beam according to the design. Yet, the lenses of split-step design are thinner, have lower insertion losses, and a greater focal depth as compared to more conventional Fresnel lenses.
