    Analysis of Fresnel Zone Plates Focusing Dependence on Operating Frequency 
    Fuster Escuder, José Miguel; Candelas Valiente, Pilar; Castiñeira Ibáñez, Sergio; Pérez López, Sergio; Rubio Michavila, Constanza (MDPI AG, 2017)
    [EN] The focusing properties of Fresnel Zone Plates (FZPs) against frequency are analyzed in this work. It is shown that the FZP focal length depends almost linearly on the operating frequency. Focal depth and focal ...
