A Wideband Quad-Polarization Reconfigurable Metasurface Antenna
IEEE Access, 2018 A low-profile wideband metasurface antenna with quad-polarization reconfiguration ability is presented in this paper. The proposed metasurface antenna is composed of a square patch, a metasurface formed by a lattice of 4 × 4 periodic metal plates,

First M87 Event Horizon Telescope Results. IX. Detection of Near-horizon Circular Polarization
The Astrophysical Journal Letters, 2023 Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polarization have further identified a coherent spiral pattern around the black ...

Interstellar Circular Polarization [PDF]
Monthly Notices of the Royal Astronomical Society, 1972 This paper shows that optical observations of circular polarization produced by aligned interstellar grains could yield valuable information about the grain material. The interstellar medium is known to be linearly dichroic from observations of interstellar linear polarization.

Circular Polarization in Scintillating Sources [PDF]
Symposium - International Astronomical Union, 2001 We discuss the detection of variable circular polarization (CP) in several scintillating radio sources: PKS 1519-273, PKS 0405-385 and Sgr A*. In all cases the CP is variable, with the fractional variability in the CP greatly exceeding that in total intensity.

Dispersion Analysis of Twist-Symmetric Dielectric Waveguides
Photonics, 2021 We propose a circular twist-symmetric dielectric waveguide that is polarization-selective. In the practical implementation of optical fibers, a selective circular polarization is more convenient than its linearly polarized counterpart where previous ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin
Molecular Oncology, EarlyView.The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.
