Advanced Electronic Materials, EarlyView.A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish

Comparison of Target Detectors to Identify Icebergs in Quad-Polarimetric L-Band Synthetic Aperture Radar Data [PDF]
, 2021 Icebergs represent hazards to ships and maritime activities and therefore their detection is essential. Synthetic Aperture Radar (SAR) satellites are very useful for this, due to their capability to acquire data under cloud cover and during day and night

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Invariance Properties and Measurement of Correlation Between Two Propagating or Evanescent Waves
Laser &Photonics Reviews, EarlyView.This work analyses the strength of correlation between two propagating or evanescent plane waves generally expressed in different frames. Interferometric and nanoscattering‐based methods, respectively, are demonstrated for their measurement. The results show that the applied measure of correlation remains invariant under unitary polarization ...
