  2. XPIC - Wikipedia

    en.wikipedia.org/wiki/XPIC

    XPIC, or cross-polarization interference cancelling technology, is an algorithm to suppress mutual interference between two received streams in a Polarization-division multiplexing communication system.

  3. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    cross linear polarized. Most sources of light are classified as incoherent and unpolarized (or only "partially polarized") because they consist of a random mixture of waves having different spatial characteristics, frequencies (wavelengths), phases, and polarization states.

  4. Cross-polarization - Wikipedia

    en.wikipedia.org/wiki/Cross-polarization

    Cross-polarization (CP), originally published as proton-enhanced nuclear induction spectroscopy (PENIS) [1] [2] is a solid-state nuclear magnetic resonance (ssNMR) technique to transfer nuclear magnetization from different types of nuclei via heteronuclear dipolar interactions.

  5. E-plane and H-plane - Wikipedia

    en.wikipedia.org/wiki/E-plane_and_H-plane

    Co-polarization (co-pol) and cross-polarization (cross-pol) are defined for the radiating E and H planes. These directions are defined in spherical coordinates corresponding to the spherical wavefronts of the propagating wave.

  6. Cross-polarized wave generation - Wikipedia

    en.wikipedia.org/wiki/Cross-polarized_wave...

    Cross-polarized wave (XPW) generation is a nonlinear optical process that can be classified in the group of frequency degenerate (four-wave mixing) processes. It can take place only in media with anisotropy of third-order nonlinearity.

  7. Parabolic antenna - Wikipedia

    en.wikipedia.org/wiki/Parabolic_antenna

    If the signal from one polarization channel is received by the oppositely polarized antenna, it will cause crosstalk that degrades the signal-to-noise ratio. The ability of an antenna to keep these orthogonal channels separate is measured by a parameter called cross polarization discrimination (XPD). In a transmitting antenna, XPD is the ...

  8. Polarization-maintaining optical fiber - Wikipedia

    en.wikipedia.org/wiki/Polarization-maintaining...

    In fiber optics, polarization-maintaining optical fiber (PMF or PM fiber) is a single-mode optical fiber in which linearly polarized light, if properly launched into the fiber, maintains a linear polarization during propagation, exiting the fiber in a specific linear polarization state; there is little or no cross-coupling of optical power ...

  9. Horn antenna - Wikipedia

    en.wikipedia.org/wiki/Horn_antenna

    Corrugated horns have wider bandwidth and smaller sidelobes and cross-polarization, and are widely used as feed horns for satellite dishes and radio telescopes. Dual-mode conical horn – (The Potter horn [ 15 ] ) This horn can be used to replace the corrugated horn for use at sub-mm wavelengths where the corrugated horn is lossy and difficult ...
