Metasurface Doppler Cloak for Broadband Radar Stealth
Advanced Physics Research, EarlyView.Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...

Archaeological Prospection, EarlyView.ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Higher-resolution wavefront sensing based on sub-wavefront information extraction
Frontiers in PhysicsThe limited spatial sampling rates of conventional Shack–Hartmann wavefront sensors (SHWFSs) make them unable to sense higher-order wavefront distortion.

Fabrication of Biocompatible Helical Fibers Using an Optical Vortex Beam
Chemistry – An Asian Journal, EarlyView.A helical gel fiber was fabricated through the photopolymerization of poly(ethylene glycol) using an optical vortex beam. The helical structure was imparted during photopolymerization because of the orbital angular momentum of the optical vortex beam.
