High-efficiency focusing and imaging by dielectric kinoform zone plate lenses with soft X-rays [PDF]

open access: yesJournal of Synchrotron Radiation, 2023
With fast advances in enhancing the focusing/imaging resolution of Fresnel zone plate lenses toward sub-10 nm, low diffraction efficiency in connection with their rectangular zone shape still remains a big issue in both soft and hard X-ray microscopy. In

Design of Acoustical Bessel-Like Beam Formation by a Pupil Masked Soret Zone Plate Lens [PDF]

open access: yesSensors, 2019
The image performance of acoustic and ultrasound sensors depends on several fundamental parameters such as depth of focus or lateral resolution. There are currently two different types of acoustic diffractive lenses: those that form a diffraction-limited

On the Design of Soret Zone Plates Based on Binary Sequences Using Directional Transducers

open access: yesSensors, 2021
In this work, we analyze the effect of the distribution of transparent Fresnel regions over the focusing profile of Soret Zone Plates (SZP) based on binary sequences. It is shown that this effect becomes very significant in those fields where directional
