Optical Fresnel zone plate flat lenses made entirely of colored photoresist through an i-line stepper by Ryohei Yamada, Hiroyuki Kishida, Tomohiro Takami, Itti Rittaporn, Mizuho Matoba, Haruyuki Sakurai, Kuniaki Konishi

“…In this study, we present a simplified method for fabricating visible Fresnel zone plate (FZP) planar lenses, a type of diffractive optical element, using an i-line stepper and a special photoresist (color resist) that only necessitates coating, exposure, and development, eliminating the need for etching or other post-processing steps. …”

Inverse design of high-NA metalens for maskless lithography by Chung Haejun, Zhang Feng, Li Hao, Miller Owen D., Smith Henry I.

“…We demonstrate an axisymmetric inverse-designed metalens to improve the performance of zone-plate-array lithography (ZPAL), one of the maskless lithography approaches, that offer a new paradigm for nanoscale research and industry. …”

A metalens for detecting fractional-order optical vortices by A.G. Nalimov, V.V. Kotlyar, Y.V. Khanenko, S.D. Poletaev

“…The metalens is based on a spiral zone plate with a topological charge of 1.5. A change in the topological charge of the incident beam is numerically shown to lead to an off-axis shift of the focal spot from the center, with the intensity maximum value also changing. …”

Probabilistic estimation of rheological properties in subduction zones using sequences of earthquakes and aseismic slip by Tobias Köhne, Rishav Mallick, Mark Simons

“…In this study, we present a framework to estimate key rheological parameters of a subduction zone plate interface using simulations of sequences of earthquakes and aseismic slip, constrained by pre- and postseismic surface displacement timeseries. …”
