Cross polarization of the transmit and receive antennas significantly diminishes the surface reflection integrated at the receive antenna. The angle of the transmit and receive antennas in a cross polarization configuration is inherently 90 degrees; at different azimuth angles, a contrast in the ...
The Relation Between Co- and Cross-Polarizabilities of Small Conductive Bi-Anisotropic ParticlesPolarization of small complex-shaped conductive particles by external time-harmonic electric and magnetic fields is considered. An original approach to excitation of particles in quasistatic magnetic fields is ...
and many functional optical elements have been designed and investigated. Commonly, the co-polarization and cross-polarization lights will coexist in the transmitted fields. Here, we propose a planar metalens composed of L-shaped nanoholes

Due to their greater vulnerability to cross-polarization interference, 64-QAM systems will require a cross-polarization interference canceller (XPIC) for virtually all links. Cancellers of this kind are paving the way to bandwidth efficiencies of up to 10 bit/s/Hz, without requiring 4096 modulation...

59Co second‐order quadrupolar effects in the 13C cross‐polarization magic angle spinning NMR spectra of the cobaltocenium salts [Cp* 2Co]+[PF6]− and [Cp*CpCo]+[PF6]−doi:10.1002/(SICI)1097-458X(199908)37:83.0.CO;2-NNMR
Samples were freeze-dried, packed into NMR rotors, and minimally hydrated (1 mg of water per mg of peptide). Measurements were performed on an 11.75 T Bruker Avance III spectrometer with a 3.2 mm Bruker MAS probe. Quantitative 1H-13C CPMAS (cross-polarization magic angle spinning)...
Overall water splitting test was carried out in two electrode systems, and polarization curves were recorded with a scan rate of 10 mV s−1. The stability was characterized by chronoamperometry and chronopotentiometry at different potential (1.633, 1.721, 1.861 V) for 21 h, diffe...
Individual health behaviors related to COVID-19 have been attributed to complex social phenomena, including inconsistent recommendations by government entities early in the pandemic, mistrust of the scientific community, political polarization, and unclear or incorrect guidance from other sources.6-8COVID...
