Reinforcement Learning Enabled Nanophotonic Devices
Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components

Radio Polarimetry of the ELAIS N1 Field: Polarized Compact Sources [PDF]
The Astrophysical Journal, 2007 We present deep polarimetric observations at 1420 MHz of the European Large Area ISO Survey North 1 region (ELAIS N1) as part of the Dominion Radio Astrophysical Observatory Planck Deep Fields project. By combining closely spaced aperture synthesis fields, we image a region of 7.43 square degrees to a maximum sensitivity in Stokes Q and U of 78 microJy/

The Polarizability Vector: A Polarimetric Observable for Characterizing Anisotropic Nanoparticles
Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.We find an overlooked observable in Nanophotonics that characterizes the optical response of anisotropic nanoparticles from simple polarimetry measurements. ABSTRACT The optical properties of anisotropic nanoparticles (NPs) are often characterized by two principal components of their polarizability tensor.

Advanced Optical Materials, Volume 14, Issue 7, 16 February 2026.Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.

General Calibration Algorithm for Single-transmitting-dual-receiving Polarimetric SAR System
Leida xuebao, 2012 The single-transmitting-dual-receiving polarimetric SAR system has only two receving channels, which induces lack of prior information for calibration. Due to the polarization diversity of this kind of system (which operates on different dual and compact
