Imaging Nanoscale Magnetic Structures With Polarized Soft X-Ray Photons
Imaging nanoscale magnetic structures and their fast dynamics is scientifically interesting and technologically of highest relevance. The combination of circularly polarized soft X-ray photons, which provide a strong X-ray magnetic circular dichroism ...

Abstract The Ecuadorian margin is a forearc‐arc system shaped by oceanic terrane accretion and Carnegie Ridge subduction, yet the accretion mechanism and ridge subduction extent remain poorly constrained. Using teleseismic P‐wave receiver functions from dense seismic arrays, we image velocity discontinuities within the overriding plate and subducting ...

This study demonstrates, for the first time, a 3D volumetric cylindrical vector beam (CVB) multicasting architecture that employs multichannel array modes with an operational dimension of 3 × 3 × 5 as information carriers. This approach offers substantial potential for high‐capacity information dissemination in mode‐multiplexed communication networks ...

Nonlinear fresnel zone plate reflector [PDF]
This paper describes a nonlinear Fresnel zone plate reflector designed to operate at 2.8GHz. The alternating Fresnel zones of the reflector are made from two different nonlinear metamaterials: one that reflects like a short circuit at low incident power levels and another that reflects like an open circuit.

Scalable fabrication of single- and multi-layer planar lenses on fiber imaging probes
We present a novel, scalable method for fabricating single- and multi-layer planar lenses on 125 μm-diameter fiber imaging probes, demonstrating preliminary capabilities for both lateral imaging (e.g., confocal microscopy) and axial imaging, using ...
