When these focal distances are linearly distributed within the sectors, dual focus is obtained. Besides, we explore the possibility to generate an extended depth-of-focus lens by using a cubic distribution of the focal distances assigned to the sectors and optimizing the weight factors given to the terms of the cubic polynomial. Finally, numerical simulations based on the Rayleigh-Sommerfeld approach are carried out and experimental verifications by using a Spatial Light Modulator are performed, showing high agreement. The proposed kind of zone plate has potential applications in different research fields such as microscopy, lithography, data storage, or imaging. 000118045 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-20R$$9info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/DPI2016-75272-R$$9info:eu-repo/grantAgreement/ES/MINECO/RTC-2019-007113-3 000118045 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000118045 590__ $$a5.0$$b2022 000118045 592__ $$a0.874$$b2022 000118045 591__ $$aPHYSICS, APPLIED$$b40 / 160 = 0.25$$c2022$$dQ1$$eT1 000118045 593__ $$aAtomic and Molecular Physics, and Optics$$c2022$$dQ1 000118045 591__ $$aOPTICS$$b18 / 99 = 0.182$$c2022$$dQ1$$eT1 000118045 593__ $$aElectronic, Optical and Magnetic Materials$$c2022$$dQ1 000118045 593__ $$aElectrical and Electronic Engineering$$c2022$$dQ1 000118045 594__ $$a8.3$$b2022 000118045 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000118045 700__ $$aSanchez-Brea, L. 000118045 700__ $$aGomez-Pedrero, J. 000118045 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
